Talk about a bad gal, RiRi!

Rihanna is never one to hold back, and in her new music video "FourFiveSeconds" with Paul McCartney and Kanye West, her cleavage is on full display as she dons nothing but Yeezy's jacket! We wonder how Kim feels about this?

"This is the first song that my fans are going to hear from the new album and the first visual they see," the Bajan beauty explained about the tune. "FourFiveSeconds" is the lead single off Rihanna's eighth studio album, Home.

A Beatle, a rapper, and bad ass b**ch is the recipe for a hit!

Paris Hilton always knows how to get some attention -- today it was with her tatas!

Along with the sexy pic, the 34-year-old wrote, "'#GlamTime', Paris."

The socialite was primping before her photoshoot in which she dressed up like a sexy business lady.

We don't know what the photo shoot was for but we think it's some promo shoots for her rising DJ career.

Recently the 34-year-old has been linked to an Aussie model, 18-year-old Jordan Barrett. The twosome got up close and personal several times during Milan Fashion Week in Italy last month.

It doesn't matter how you feel about Kim Kardashian and Kanye West -- their daughter Nori always manages to melt our hearts!

Before the Super Bowl on Sunday, Kim and Kanye took their little girl to a wildlife park in Arizona, and Kim captioned the above shot, "At the zoo with my boo and my baby boo." So clever, this one!

Kimye flew to Phoenix on a private jet, and after visiting with the animals, the group started getting ready for the big game. Kim shared an adorable snapshot of Nori helping her get ready and wrote, "Finishing touches by my new make up artist." Aww! And as annoying as Kim's selfies are, we did like that she totally made fun of herself in that T-Mobile commercial...

Bobbi Kristina Brown, the daughter of Bobby Brown and the late Whitney Houston, is currently in a medically induced coma, but her family is remaining hopeful that the 21-year-old aspiring singer will pull through.

A rep for the family said in a statement yesterday, "Bobbi Kristina is fighting for her life and is surrounded by immediate family. As her father already stated, we are asking you to honor our request for privacy during this difficult time." On Monday evening a source close to the family told CNN that Brown had "opened and closed her eyes a few times," but noted that doctors reportedly told family members "not to read too much into it."

On Saturday Brown's husband Nick Gordon found the starlet lying facedown in the bathtub of their Roswell, Georgia home, and he administered CPR until the police arrived. According to authorities, no drugs were found “out in the open” during the preliminary investigation of Brown’s home, and the incident is still being investigated.

Three years ago Houston was found dead in her bathtub at the Beverly Hills Hotel.

Mila Kunis makes an appearance on The Ellen DeGeneres Show this morning, and the gorgeous starlet chats about everything from her new movie to being a mom.

Mila joked that she got a great push gift, and revealed that daughter Wyatt Isabelle might be on track to be the same size as dad Ashton Kutcher. Well, maybe. "Newborn never happened," she said. "Newborn diapers never happened. And newborn clothes never happened. 0-3. She’s 4 months old and wears 6 month clothing. 6-9. She’s a big girl ya’ll."

So what about taking time off to take care of her little girl? Mila said:

"No, listen. Here’s the thing when I go back to work full time and have to have 17 hour work days I’m gonna need somebody to come and help me because I can’t do both. But because I’m in a very specific place in my life where I could take time off. I did. And I don’t think that everybody has that privilege. I think that people now a days have to go back to work right away and I didn’t so I took advantage of it like I love the fact that the first 3 months she and I were up every night. And I figured her out and she figured me out and she now sleeps in her own crib in her own room and I will never have that time again so for me it was a really nice three months."

Gwyneth Paltrow wishes she could have said that! And as far as Ashton's parenting skills, Mila had nothing but good things to say about her longtime love.

"He is an amazing Dad -- I wouldn’t have done this by myself," she gushed. "He is 100% present. You know, he always said that, I am breastfeeding so I provide the food for the baby. So his whole thing is changing diapers. He’ll never be able to feed her in the early stages, now he can because she’s partially bottle feed. But the second she was born he changed the first diaper. And has changed multiple diapers ever since. If he’s home he changes the diaper. He became a master swaddler. He can swaddle anyone’s baby. Like if you’re baby needs to be swaddled he will do it." Who would have guessed!

But when Ellen asked whether Mila and Ashton were legally married, the actress weaseled her way out of answering the question ... Check out the video above to see what she had to say!

We already knew Bruce Jenner was going to share the details of his male to female transition with a news outlet, but now it's been confirmed that the reality star will sit down with Diane Sawyer to discuss his story.

"Diane has always been very supportive of the LGBT community," an insider tells Us Weekly. "She has been honored by GLAAD." The interview will air in May, and a source tells Page Six that Bruce will start filming the interview this week. And not only that, but the transition will be the focus of Bruce's new series on E!, along with Keeping Up With the Kardashians. "The world will see his full transformation," a source tells Us. "It's a docuseries featuring the Jenner family talking about Bruce 'coming out.'"

Last week Kim Kardashian hinted that something was up when she said Bruce would share his story when he was ready, calling his changes a "journey." When asked about a recent photo that Khloe posted of all the girls with Bruce, Kim added, "That was not like a secret message like, 'We support Bruce.' Of course we support Bruce 100 percent. He's our dad so we support him no matter what, and I think when the time is right, he'll talk about whatever he wants to talk about."

We can't wait to hear it! But now that the cat's out of the bag, can someone in the Kardashian family get Bruce some sexier threads? He's doing great with the lips and hair, but his baggy jeans aren't the best look...

Kylie Jenner does NOT look happy! Just days after news broke that her father Bruce Jenner has been transitioning into a woman for the past year, the 17-year-old was looking distraught when she grabbed lunch in Calabasas, Calif., on Monday afternoon.

We'd just like to point out that -- other than looking pretty unhappy -- Kylie's face (but not neck) are about five shades paler than usual. Perhaps now Kylie is transitioning into a vampire?

It's been a jarring weekend for the teen reality star and we aren't surprised she looks like she's having a rough go of it.

Over the weekend, People.com reported that Bruce is ready to go public with his transition to being a woman and will film his journey for a docu-series, which is set to air this year. "It will air when he is ready to be open about his transition," a source close to the family tells People. "But he's acting more and more confident and seems very happy."

He's been going through the process rather slowly, out of respect for his family, according to the report. He didn't want to shock his six kids and ex-wives by changing overnight. A source tells the mag: "He's being very smart about and also respectful about his transition. Instead of completely shocking everyone, his changes have been subtle, and his family has had the chance to slowly get used to his new looks and life."

Sounds like there's always a lot going on with the Kardashian/Jenner fam!

He knows how to turn up the heat!

Justin Bieber cranked the heater on his pool to make it a giant jacuzzi in Beverly Hills over the weekend, and the Canadian stud looked mighty sexy as he relaxed in his steamy surroundings! The only thing The Biebs was missing was a girl to get wet with him! Where was Hailey Baldwin? Or Kendall Jenner?

One person we know that is seemingly over sexy swims with JB is his ex Selena Gomez! The "Come & Get It" singer has been flaunting her new romance with DJ Zedd all over town, and it has to be making the "Boyfriend" crooner slightly jealous. "Her number one man right now is Zedd and she’s falling hard for him. He’s good at turning lemons into lemonade. Selena says Zedd makes her feel happy and peaceful, and that being with him is addictive — in a good way," a source dished to Hollywood Life. "In fact, when she’s with Zedd, she tries not to talk about Justin at all. She is determined to make it work with Zedd," the source added.

The womanizing singer could have Selena back in two seconds if he wanted her!
