Kaley Cuoco and Ryan Sweeting couldn't make it last ... The Big Bang Theory actress announced she and her hubby of 21 months will divorce, in a statement to People:

"Kaley Cuoco and Ryan Sweeting have mutually decided to end their marriage. They ask for privacy at this time. No further statement will be issued regarding this matter."

Cuoco, 29, and the tennis player, 28, wed Dec. 31, 2013 after a whirlwind romance. Kaley has since deleted all Instagrams with her former hubby.

As she's losing a husband, however, Kaley's taking on a new pet! She posted this pic of her new horse, Zaza, on Saturday. Something else significant about the pic? No ring! Cuoco ditched her diamond wedding ring just a day after announcing her split.

In some sort of mixed up world, Kylie Jenner has somehow emerged as the most popular member of the Kardashian/Jenner klan. Everything is topsy turvy!

In a vlog called "You're in Bed With Kim and Kylie," Kim jokingly asks her 18-year-old sister about her rapidly increasing social media following. The 34-year-old says to her sis, "How do you feel now that you have dethroned me?"

In the segment which features the two of them in bed together, Kylie, who has the hottest new app out of all the sisters, just smiled awkwardly and refused to comment.

The pregnant reality star then went on as if she was trying to put her uncomfortable sister at ease with her newfound popularity, but also making sure she put Kylie in her place about Kim still being on top. Kim said, "I love it, like, I love it. I need some time off. I mean honey, let's be real, you've got to put in a few more years before you actually dethrone me. But I give my baton to you. Who better to pass on knowledge to my baby sister, rather than a random non-family member."

Kim must really want us to know she's totally cool with Kylie's soaring status. Kanye West's lady love insisted, “You guys, this is amazing. I give Kylie all my tricks, I give her all my tips. I give her everything, and more. She is so, like, deserving. If I would want anyone to follow in my footsteps, anyone to borrow my clothes, anyone to like share my glam team it is Kylie, King Kylie."

Umm is it just us or is the basic gist of Kim's not-so earnest sounding speech: Yes, Kylie is really blowing up, but that's only because she stole all my tips, my clothes, my style and my make up artist, which means she owes me everything for teaching her everything she knows.

Kim also addressed the engagement elephant in the room. In the vid, Kim asked Kylie,"Why did Tyga call you his fiancee? I was, like, dying to know."

Kylie's answer: "He was making fun of an Instagram he posted 30 minutes before. "He knew there was this guy who was on Instagram who was like, 'I don't like nobody. I just play with my fiancee and my little dog.'"

Umm what? That's a terrible explanation! Sorry, Ky, that makes no sense. Maybe think up a better story if you are trying to get the heat off of you when your boyfriend probably just spilled the beans about your engagement to the entire world?

She is such a natural beauty!

Karrueche Tran grabbed a pressed juice in Beverly Hills on Thursday, and the model was in quite the upbeat mood. Clearly she isn't bothered about the rumors that circulated this week that she was secretly dating Rob Kardashian.

In case you missed it, Kimmy K's little brother sent the Internet into a frenzy when he Instgrammed a text conversation between himself and Chris Brown's ex earlier this week, but the brunette beauty claims they are just old friends from high school. In fact, she says the reason she sent a selfie was because she was showing the reality star a pic of her swollen face from wisdom tooth removal surgery.

It sounds like Breezy isn't worried in the slightest that his former love could be moving on!

"Chris is laughing, damn near crying, if anyone thinks he’s threatened by Rob. No disrespect to the brother, but Rob couldn’t land Karrueche if he were a pilot. For Kae to leave Chris and try to hook up with Rob would be a serious downgrade. And if there’s one thing Chris knows about Karrueche, it’s that she likes that Hollywood life and Rob can’t give her that. Him posting pictures of Karrueche is like whatever to Chris. He knows nothing sexual will ever happen between the two of them. He’d bet all of Royalty’s custom made cars — and they’re expensive — on that!” a source dished to Hollywood Life.

We have a feeling CB will never get over her!

We're glad she's on the mend!

Kim Zolciak is still in the hospital after suffering a mini-stroke following her performance on this week's DWTS, but the reality star took to her Instagram to give us an update on her condition, and it sounds like she's on the road to recovery!

"Going in for one more procedure, things are looking up! Don't let the oxygen scare you it's just protocol," she captioned a snapshot of herself with an oxygen tube.

"I wanted [to] THANK all of you for the love! I feel so overwhelmed with all the texts, comments, etc. I'm so grateful to have all of you! #TheyDontCallMeToughieForNothing," she added.

In case you missed it, the blonde bombshell suffered the medical crisis on Wednesday, and was left unable to speak and without feeling on her left side. Luckily, those faculties have returned, but it remains to be seen if she will compete on next week's episode. Her dancing partner Tony Dovolani just paid her a visit in the hospital, which is so sweet!

Who knew the barbaric fashion practices of the Victorian era would be so on trend in 2015?!

Khloe Kardashian is keeping up with this ridiculous waist training fad by flaunting her ridiculously small corseted waist in a colorful selfie. Umm that looks painful!

On Thursday, the Keeping Up With The Kardashians posted the selfie which highlights her insane curves in a neon workout ensemble and hot pink waist trainer.

Along with the snap, Khloe wrote, "Who doesn't love a good waist trainer/bathroom selfie 😝 make sure you follow my girl @premadonna87 @waistgangsociety for the best trainers in the game. Head over to www.whatsawaist.com to get hooked up!! ❤️❤️❤️ lets snatch that waist 💋💋💋."

This isn't the first waist-cinching selfie the celeb has shared -- three weeks ago, Khloe posted a pic of her in an all-black ensemble, rocking another corset.

In that photo, she wrote, "I'm obsessed with the gym but a little extra help never hurt nobody… once you try it, you will become obsessed!!!"

The controversial beauty practice has us all at the X17 offices baffled -- but those Kardashian gals seem to swear by it.

If it wasn't for The Biebs, she would have nothing to talk about!

Selena Gomez couldn't help but praise her ex-boyfriend Justin Bieber when chatting with the New York Times about his recent comeback, and while we think it's sweet, we can't help but wonder if part of her motivation for the sweet sentiment is to get press for her new single.

"While people were writing that I was stupid for being in [the relationship], this is what I always saw in him. I’m like, duh!" she gushed.

The "Come & Get It" songstress went on to explain how her romance with JB inspired her new album Revival. “It’s all part of my story. I’m growing and changing. I was in a relationship, and I was being managed by my parents, and I was still under Hollywood and Disney, and I was being held to this expectation of being the good girl," she lamented.

The singer managed to come out on the other side, though, and credits that strength to her ability to be uncomfortable while much needed change occurred.

"I knew deep down that this wasn’t what I wanted to do — being exhausted of forcing something that wasn’t right, even in my personal life. I had to have moments where I was crying and I was like, ‘Why am I not in love with what I do?’ I was forced to get very uncomfortable for a while in order to make the decisions I made. I definitely remind myself that I’m in control. I feel like ultimately if I sit down and I think about a decision I need to make, it’s really within myself. I make the decision. Everything goes through me," she concluded.

This sounds good, but you know deep down she's still got a terminal case of Bieber fever!

So this is how she maintains her model physique!

Kendall Jenner accidentally hit the curb in her Range Rover while driving in Beverly Hills yesterday, and after she inspected the damage done to her pricey ride's rims, she headed to the juice bar with a pal to get a healthy drink and blow off some steam. The cat walker showed off her incredible bod in a grey spandex outfit, and it's not hard to see what rumored new beau Orlando Bloom sees in her!

The leggy brunette is the most private of the Kardashian clan, but in a sneak peek of the new season of Keeping Up with the Kardashians, she admits she's struggling with coming to terms with her father Caitlyn's transition.

"I'm alright. I feel like it's a process. It's something to get used to, for sure. But the only thing is, I haven't met her…It's also a letting-go thing. It's like when you officially meet her it's like, he's gone. I think that's what I'm holding on to. That's why I've taken so long to meet her," she confesses to sister Khloe during one scene.

We've said it before and we'll say it again... no more bucket hats!

Rihanna arrived at LAX to catch a flight out of town today, and the singer dressed a little too casually for her travel day in sweatpants, a tank top with no bra, and Puma slides. Her lack of undergarments put her nipple piercing on full display, and clearly a bar through your nip is the new hot trend. How Kendall Jenner of her!

RiRi's new man Travis Scott didn't accompany her, but the two are reportedly still going strong. In fact, he's been cast as the co-model for her Puma collection, of which she serves as the creative director. Something tells us the Bajan beauty had a hand in getting him that gig!

The "BBHMM" songstress isn't stopping with just one role in the industry, though. She established The Fenty Corp to make her own clothing line, and she recently announced they are ready to start hiring by posting a hilarious glimpse at the employee handbook! Among the rules? "Normal size people get 15 minutes for lunch to get a balanced meal to maintain their figure. Fat people get 5 minutes for lunch, because that's all the time needed to drink a Slim Fast."

She really loves to get a reaction out of people!
