After being humbled at his Comedy Central Roast in Hollywood on Saturday afternoon, it seems like Justin Bieber wanted to get the heck out of town -- so he jetted off to Las Vegas and had a belated 21st birthday bash at Omnia at Caesars Palace. Not a bad way to spend your weekend!

Bieber's roast was taped at the Sony lot in Los Angeles, and the Canadian crooner had to endure a number of brutal jokes in front of an audience that included stars like Will Ferrell, John Legend, Chrissy Teigen, Kourtney Kardashian and Dave Chappelle. At the end of the roast Biebs told the crowd, "Damn, you guys were brutal. This was supposed to be a birthday present. When people ask me what I got for my 21st birthday, I'll tell them I got my d*ck kicked in. I should have known."

But then the pop star seemingly apologized for acting out over the last few years! "I turned a lot of people off the past few years…There was no preparing me for this life. I got thrown into this, 12 years old," he added. "There are moments I’m proud of and things I’ve done that don’t define who I am. I look forward to being someone you’re proud of…I’m excited to see what’s next. You have my word — I will not end up broken, pathetic, bitter or sitting on someone else’s roast. I’m at a moment of change. This is a new day."

Host Kevin Hart kicked off the night by saying, "Tonight we are gonna do what parents and the legal system should have done a long time — give the boy an *ss-whuppin he deserves." And that's exactly what they did, but it seems like Selena Gomez got dragged through the mud as well! "Selena wanted to be here, but she’s dating men now," comedian Jeff Ross joked. "Is it true you dumped her because she grew a moustache before you?" Ross then made a racially-charged joke, but after that it seems like the bulk of the heat was on the Biebs.

We can't remember the last time a celeb split got this ugly -- and we have a feeling it's only going to get worse!

Pamela Anderson filed for divorce from Rick Salomon in February for the third time (they've been married twice now), and now she's filed a restraining order against her ex-husband -- and some dirty details about their marriage have been leaked via court documents.

In the legal docs Anderson included emails that Salomon allegedly sent, in which he claims she had several abortions during their marriage. "I did not [know] she was a serial baby killer to her husbands...she should be locked up," he reportedly wrote in one, adding that Anderson begged him for a baby during their first marriage, but then terminated the pregnancy. Salomon also dragged Anderson's ex-husband Kid Rock into the mess and added, "You never disclosed to me that you (redacted) a baby when you were married to kid rock. I heard you begged him to get pregnant with him too. I also heard it might have also been twice with him."

As far as the real reason why she's getting a restraining order, Anderson claims that Salomon spit in her face, and tried to strangle her and smother her with a pillow when the two had sex in January. She also claims that he has called her an "ugly old b*tch" and "crack wh*re." Yikes! What next?!

Madonna and her youngest son David jetted out of New York City's JFK International Airport on Saturday, and we're not sure where they're headed, but it looks like he had his mom all to himself! It's not clear where sister Mercy was, but David's older siblings Rocco and Lourdes were probably off doing their own thing -- after all, Lola is in college now! We can't believe how fast all of Madge's kids are growing up...

While the 56-year-old pop star is still widely respected (even after that embarrassing fall at the BRIT Awards), apparently she feels like she's being discriminated against due to her age. Madonna has accused BBC Radio 1 of "ageism" after a programmer at the station announced that they were going to pass on playing "Living for Love" so that they might appeal to a younger audience. Madonna called the decision "discriminatory and unfair" and chatted with The Sun about the drama.

"I was like, 'Wait a second. Shouldn't it have to do with whether you wrote a good, catchy pop song?'" she said. "My manager said to me, 'If you're not in your twenties, it's hard. You might get your record played in your thirties. There's a handful of people who do - Pharrell got lucky. But if you're in your fifties, you can forget it'," Madonna said. "I didn't know it was anything to do with my age. I just do my work. We've made so many advances in other areas - civil rights, gay rights - but ageism is still an area that's taboo and not talked about and dealt with."

Leave it to Madonna to talk about it -- and deal with it!

After getting a peek at Jessica Simpson and Eric Johnson's semi-pornographic Instagram posts on Valentine's Day, it became clear that their sex life is sizzling, but it's also nice to see them getting all dolled up and going on a romantic date! Jessica's body looked amazing in the Fifty Shades of Grey-themed snapshots, but the ass grabbing and spread legs were a little too much for us. I mean, this isn't Kimye we're talking about here!

On Friday afternoon the couple went to lunch in New York City, and after Jess had a meeting and and outfit change, they headed to dinner. Jess has been busting her booty to shed the last of her pregnancy weight, and she's definitely reached her goal -- and then some! Her thigh boots and eye makeup are giving us some major Pamela Anderson vibes, and we honestly can't remember the last time we saw the mother of two looking this sexy. Good for her!

Jennifer Lopez went to a business meeting in Burbank on Friday, and the 45-year-old superstar looked amazing in a short printed dress and heels. Even if she was 30 we'd think she had an incredible body ... it seems like she's only getting better with age!

We're not sure what the meeting was about, but it was recently reported that J. Lo is in talks to appear on an episode of Empire next season. The singer/actress had a meeting with executive producer/star Terrence Howard, and according to The New York Post, creator Lee Daniels "would love to have Jennifer Lopez on the second season."

J. Lo is currently developing a new series for NBC called California and she's still a judge on American Idol, so we're not sure when she'd have time for that -- but it would be amazing!

We love the fact that Lenny Kravitz and Lisa Bonet are friendly exes! And we know she's currently married to super hunky star Jason Momoa, but we can't help but notice how good she looks with her former husband!

Lenny and Lisa split in 1993 after six years of marriage, but seeing as they have a daughter together (you know, the totally gorgeous and hip Zoe Kravitz?), they've had plenty of reasons to keep things amicable over the years. On Friday the duo went to lunch in West Hollywood, and it's funny, because in her recent feature in Ocean Drive magazine, 26-year-old Zoe chats all about family life and how tight her parents are.

"They have so much love for each other," she said of Lenny, Lisa and Jason. "It makes things so easy that my parents are still very close. My dad and my step-dad get along really well, and my dad loves and is close with my [step]brother and sister. It's really beautiful ... As long as everyone can be in the same room together, and have love for each other, it's totally healthy. Mom and dad remain tight and loving, and [I] spent many years with each staying in Los Angeles until age 11 and then relocating with [Lenny] to Miami and New York."

The Biebs is legal!

On Friday night the 21-year-old pop superstar partied at The Nice Guy in Hollywood and literally we got weak in the knees after getting a glimpse at his picture-perfect smile! Before the Biebs was able to hop in his chauffeured SUV, he was mobbed by a few overzealous fans trying to snap selfies. Can't say we blame them!

In other news, we already saw Justin's smokin' hot Men's Health spread, but what we didn't see was how mean the accompanying article was! Apparently the writer is NOT a Belieber, as he took every possible opportunity to slam the star. "It's not that you don't like Justin Bieber. You actually find him offensive," Oliver Broudy writes. "Why? Because his success primarily depends on skillful producers and shrieking tweens? Because he managed to steal the attention of half the planet's girls by basically becoming one of them?"

Um, ouch! But we're thinking Biebs is having the last laugh -- and maybe he'll use the same line on Broudy that he did on Selena Gomez back in the day? You know, "Can't hear you over my cash, babe!"

Kim Kardashian has busted out of her clothes before (with her curves, it's inevitable!) but yesterday even she seemed surprised about her latest wardrobe malfunction. The sexy reality TV starlet was about to hop into her Mercedes SUV when she noticed a problem with her outfit, at which point she had one of her staffers stuff her back into her corset top.

A few minutes later Kim and Kanye cruised down to Taco Bell to grab a bag of grub from the drive-thru, and we can't help but wonder if this might be the start of pregnancy cravings. On Friday morning X17 photographers caught Kim leaving a fertility clinic, and Kim usually eats pretty healthy, so Taco Bell is a pretty interesting choice. Plus, both she and Kanye have been blabbing about how much sex they're having desperate they are to give daughter Nori a sibling, so we wouldn't be surprised!
