Real men don't kiss and tell, but he's not exactly our definition of classy so this doesn't surprise us!

Mario Lopez revealed in his memoir Just Between Us that he had a one-night stand with an unnamed "mega pop star", and now Us Weekly is reporting that the lady in question was none other than Miss Britney Spears!

"I'm trying not to give too much away without giving too much away. It was maybe six or seven years ago… eight years ago?" the TV host dished to Ellen Degeneres earlier this month. The timeline of the hook up would make sense, as both celebs were single at the time. The pop princess split from Kevin Federline in 2006, and the Extra star was on a break from then-girlfriend Karina Smirnoff.

He's a married father-of-two, and we think he should have kept his mouth shut out of respect for his family!

Juliette Lewis has released a statement of sorts about the passing of her August: Osage County co-star Misty Upham, and she seems to think the late actress was murdered!

Upham, 32, had been missing since October 5, but her body was found "at the bottom of a 150 [foot] embankment near the White River," according to local authorities. Misty's father Charles told The Hollywood Reporter that he believed his daughter could have be suicidal after not taking medication for bipolar disorder.

Lewis posted the photo above and wrote:

"Misty Upham survived many things that many don’t early on in life,” Juliette wrote in an Instagram post. “She fought for the voiceless fiercely. She understood suffering and the deepest pain. She had a presence everyone saw and felt. It is this presence that will continue. Out of the dark space in which her light got dimmed. I will remember her as tuff. Wise. Funny. Spiritual. And hopeful. This is another great reminder to call and check on someone when you think to. Not when its too late. RIPMistyUpham."

But it was her tweets that sent a much stronger message:

"#RIPMistyUpham I am in shock and greif [sic]. I pray the police do a murder investigation. They're saying not "foul play" when of course it is ... Misty spoke out alot against injustices within Native community. And had known enemies. Police must do an investigation ... Misty told me about horrible violence she suffered on NA reservations She felt she coul be murdered! Bcuz she was vocal #ThisIsNOTaSUICIDE."

Our thoughts are with Misty's friends and family...

Rob Kardashian and Bruce Jenner aren't the only ones in the family who have undergone dramatic transformations!

In honor of Flashback Friday, here's a look at Kim Kardashian's face today (well, technically yesterday) and all the way back in 2007, with a couple of snapshots in between then. We can't believe how much the sex tape/reality TV starlet has changed over the years -- from her hair color to certain features on her face, it's like she's a whole new person!

Kim stepped out in Beverly Hills on Thursday afternoon in a sexy black outfit, but who's looking at her curvy bod when she's flashing this gorgeous smile?

Busy day for the Biebs!

Justin Bieber climbed into the ring to train with pal Floyd Mayweather yesterday, and based on this video he posted, he isn't half bad! The singer is seen moving around the ring and dodging the boxing legend's jabs, all while shirtless of course!

Later in the evening, JB reunited with troublemaking pal Lil' Twist to grab a pasta dinner in Hollywood. The bad influence friend posted the below Instagram of the pair at a restaurant, and clearly he's happy to be back in the Canadian pop star's life. "And just like that... We're bak ... Leaving a great dinner with my lil brother @justinbieber ! #Family," he captioned the snapshot. Rumors circulated months ago that Bieber's management team was making every attempt to keep Twist out of the crooner's life, because they believed he was the reason Justin was repeatedly getting into trouble.

Baby, baby, baby… TKO!

Charlie Sheen is single and on the prowl again -- Hollywood hookers, you've been warned!

Much to our great dismay, the tiger's blood drinker and all-around dandy boy has split with his porn star fiancée Brett Rossi, whose real name is Scottine Ross, just weeks before their November wedding. How can we all go on when true love like this is no more?!

Sheen told E! news, "Scotty and I had a great year together as we traveled the world and crossed a lot of things off our bucket list. She's a terrific gal—but we've mutually decided to go our separate ways and not spend the rest of our lives together."
Tears! Wailing! Gnashing of teeth! WE CAN'T SURVIVE THIS KIND OF EPIC HEARTBREAK?!

The former Two and a Half Men star doesn't seem to broken up, but added, "I've decided that my children deserve my focus more than a relationship does right now. I still have a tremendous fondness for Scotty and I wish her all the best."

The couple, who went public last November, got engaged during a Valentine's Day trip in Hawaii.

RIP True Love.

Victoria Beckham landed at Los Angeles International Airport with daughter Harper and her sons Cruz and Romeo on Thursday evening, and the group looked exhausted after jetting in from London!

But Victoria had previously flown to London from South Africa, so we have a feeling she was running on hardly any sleep at all. You'd never know though -- as usual, she looks absolutely amazing! Victoria's hubby David flew home a few hours earlier, and it appears as though their oldest son Brooklyn was staying stateside during this time, as he wasn't with either parent.

The former Spice Girl headed to Soweto, South Africa for her first trip as a United Nations ambassador last week, and she met with mothers and babies who are suffering from HIV. Victoria stopped by Bara Hospital, where she spent time with community workers from Anova Health Institute.

Last month it was announced that the British star would be an ambassador for the UNAIDS campaign, and at the press conference in New York City, Posh told the audience, "I am mother and I am a woman. I will do whatever I can to raise awareness. I feel very passionate about this. I recently visited South Africa and was so touched by the women I met and felt inspired. I came home and I knew I had to do something."

Victoria posted the below photo and wrote, "In the last 3 years @ejaf have helped over 60,000 mothers give birth to HIV free babies. X vb."

They all got somewhere to be!

On Thursday, the Kardashian girls were all about and about on seemingly different agendas. What else would you expect?

Kim and Khloe Kardashian had a sisterly reunion of sorts (more on that in a sec) at a photo shoot near downtown Los Angeles while Kourtney Kardashian, who's just about ready to pop out her third child, and Scott Disick perused through Beverly Hills.

As for Kim and Khloe's meet up, it could be purely professional as there's been rumors circling that the two haven't spoken in almost a month and a half!

They both seem to have a gripe with each other as Khloe feels like Kim's ego is at an all-time high while Kim's fed up with Khloe's inability to officially divorce Lamar Odom after everything they've been through. Add the fact that she also wasn't fond of Khloe's time with her ex-BFF Paris Hilton at a restaurant opening in Dubai last week and you have yourselves a full blown rift... possibly.

This could all be hearsay so this could all be taken with a grain of salt but one thing's for sure: time will tell!

She's simply glowing!

Earlier today, Blake Lively made it the day she would show off her growing baby bump in public for the first time when she struck a pose at the God’s Love We Deliver, Golden Heart Awards red carpet in New York City. And that floor-length, flowered Michael Kors gown ... love it!

The 27-year-old Gossip Girl star initially announced her pregnancy with husband Ryan Reynolds by posting a beautiful bump photo on her Preserve website back on October 6. She also shared a bit about what she's looking forward to the most as motherhood approaches.

“With a new baby on the way there is so much to do!" she said in a recent blog post. "But before experiencing the joy of 3am screams, seemingly impossible amounts of poop and having a favorite shirt covered in reflux.”

Sounds like she simply can't wait!
