We're not sure what on earth Miley Cyrus is wearing (or who Channing is!), but her abs look incredible and we're happy to see her smiling -- and rocking her engagement ring!

On Wednesday the 20-year-old pop superstar stopped by Jimmy Kimmel Live! in Hollywood for a taped appearance, and we spotted her giving Pharrell Williams a hug on the way in. As you know, Pharrell helped produce Miley's soon-to-be released album, and the duo also bumped into singer Robin Thicke. What are the odds?

And what about those crazy rumors that she's hooking up with Justin Bieber? Miles chatted with The Kane Show on Hot 99.5 in Washington D.C. on Wednesday and said, “I'm ENGAGED. I’m engaged. That is impossible.” Well, that and Bieber was actually leaving Diddy's son's house, NOT Miley's!

In case you're having a hard time keeping up with the Kardashians this week, the latest news is that Kanye West allegedly cheated on Kim with Canadian model Leyla Ghobadi. However, when we spotted the pregnant reality starlet hanging out with BFF Jonathan Cheban in Beverly Hills on Wednesday, she didn't seem bothered by the news -- in fact, she was laughing when we snapped the duo cruising around in her Rolls Royce.

So what's the rapper being accused of this time? Kanye and Leyla reportedly hooked up in July of 2012, and when asked about his relationship with Kim, Kanye said it was "for publicity and nothing serious." The duo had another tryst last October in New York, while Kim was shooting her reality show in Miami.

For her part, Kim said this "recent attack" is "totally without merit," but when we polled X17 readers, 64% of you are convinced that Yeezus will "never be faithful to Kim," 28% of you aren't sure, and only 8% of you think he's totally innocent. Those aren't very good odds!

Halle Berry and Olivier Martinez are expecting a baby boy!

“My son will be an American, but I remain French,” Martinez told People Magazine at the opening night of the Champs-Elysees Film Festival in Paris on Wednesday evening.

Martinez, who is serving as this year’s honorary president, added, “I’m French — it’s less important ... Meaning, I remain a Frenchman in America, but I adapt to American culture. I feel good there — but I’m still a foreigner. My son will be an American."

No word on when the baby is due, but various websites report that Halle is due in the early fall.

LeAnn Rimes was snapped running around the Meatpacking District in New York City on Tuesday afternoon, and she may have a crazy appearance schedule to promote her new album Spitfire, but she's loving every second of it! Then again, we all know LeLe loooves the attention...

The homewrecking hottie hasn't cooled off her feud with Brandi Glanville after stealing the reality starlet's husband Eddie Cibrian back in 2009, but critics are loving the heat she's bringing on her new EP. The album has received rave reviews thus far, but we have a feeling it has a lot to do with the subject of many of the songs.

"To become tabloid fodder when you have a talent you want people to hear is very frustrating," Rimes told CMT recently. "It's like 'Hey, I'm over here! I sing still!' ... Hopefully, I can take the celebrity and use it for what I need, instead of people using me. Maybe I can use all of this craziness and have people hear my music. That would be awesome, and that's my plan."

It looks like Bradley Cooper may have been a better choice than co-star Ryan Gosling for the motorcycle bandit character in The Place Beyond the Pines.

The actor rode his bright orange bike earlier today after leaving SoulCycle gym in Brentwood. He donned head-to-toe navy blue, a helmet that hid his new 'do, and a chest protector for the ride.

The Oscar-nominated star took a two-wheel tour of Paris with rumored girlfriend Suki Waterhouse in April. He also showed up to this Saturday's Spike TV Guys' Choice awards with the 20-year-old British model, who's 18 years his junior. We have to say, he looks better ridding that bike with her perched on it.

Aww, they look so in love!

Kristin Cavallari decided to share a snapshot from her wedding last weekend on her Instagram account today, and we still can't believe she's a married woman!

Clad in a strapless Monique Lhuillier dress, the Laguna Beach alum is the picture of happiness as she gets embraced by new husband Jay Cutler.

"The flowers and everything were very simple but it was very warm and cozy. It was all about the lighting and the candles and the atmosphere was just so warm. It was absolutely perfect," she tells People of her nuptials.

K-Cav's big day was intimate with just close family and friends, who dined on Southern fare and danced to a Motown band.

How did it feel after tying the knot?

"We were both just like, 'I can't believe we did it!' Especially Jay, because he's never worn a ring before. It's going to take some getting used to," she added.

Congrats lovebirds!

It's relieving to know that January Jones is a much better mom than her Mad Men character Betty Draper Francis.

The actress took her adorable son Xander shopping with her yesterday in Los Angeles' Larchmont Village. The stylish star rocked a pair of black skinny jeans, a striped sweater, and a new 'do. We love that her hair matches her son's strawberry blonde locks.

The new mom has refused to name her little boy's biological father.

"It's just not something the public needs to know," she recently told The Edit. "I don't divulge my sexual preferences. There are parts of your life -- no matter what your job -- that should remain private. When I was starting out, other actors advised me to keep certain things close to the vest. When you become a public figure people want to know everything about you, and then [they] pick it apart -- it becomes negative."

However, rumors have been swirling that Xander's dad is her ex Jason Sudekis. Check out this photo of the the Saturday Night Live star at a photoshoot in New York City yesterday and judge for yourself.

Now we know why Reese Witherspoon looked so spectacular strolling in Beverly Hills yesterday. It's all thanks to spinning!

The actress looked trim and fit while leaving a spin class earlier today in Brentwood. Wearing a hoodie, spandex, shades, and bright running shoes, the Oscar winner was less glammed up than during her last sighting, but gorgeous nonetheless. Reese seemed completely happy on American ground. Her and daughter Ava returned from their 10-day Paris getaway on Monday afternoon. The mother of three gifted the trip to her daughter after her middle school graduation.

It's safe to say that the Oscar winner is back to leading a healthy life after her May arrest for disorderly conduct. Reese was fined for obstruction of justice, while her hubby agent Jim Toth was put on probation, fined, and required to attend alcohol education classes following his DUI arrest.
