Lucky, lucky Rebel Wilson!

The 26-year-old Australian actress was at the receiving end of a kiss from hottie Zac Efron. Zac Tweeted, "I think I'm in love!"

Zac and the Bridesmaids funny lady were hanging together at the Lakers game. Talk about a great night!

Lindsay Lohan made an appearance on Late Night With Jimmy Fallon on Wednesday in New York City, and the 26-year-old starlet may be busy promoting Liz & Dick, but that doesn't mean she can't goof off a bit!

Lindsay walked up to the stage in a short wig and a bizarre all-white outfit, and Jimmy wore a similar getup for the “Let Us Play With Your Look” sketch. The duo picked out one lucky audience member to join them, and despite the chaos around him, their makeover subject maintained his composure.

Glad to see Lilo's being such a good sport about it!

Megan Fox guest stars on husband Brian Austin Green's new TBS series The Wedding Band, and this is our first look at the 26-year-old starlet's spot on the show.

Tommy (played by Green) meets Alexa (Fox) when his band, Mother of the Bride, plays a wedding at Comic-Con, and we're not exactly sure if sparks are flying between the two, but it is funny to see them onscreen together!

And who doesn't love looking at Megan, especially when she's dressed as every geek's dream girl ... check out the clip below!

On Wednesday Hilary Duff and her darling son Luca were spotted after a mommy and me class in the valley, and the former Disney star couldn't stop smiling when we snapped her picture.

Hilary and hubby Mike Comrie welcomed their first child together back in March, and since then she has spoken out about the challenges and joys of motherhood, particularly when it comes to losing the baby weight.

In last month's issue of Parents Magazine, Duff said she embraces her curves, adding, "There are some women who look the same right after [giving birth] -- I think they are freaks of nature! I don't know how that happens. I'm not one of those people. It takes your body nine months to get there -- really ten months. So I'm trying to be patient but I'm working hard. And I think now more than ever, I appreciate my body and what it's done for me."

Miley Cyrus and her mom Tish were snapped at the recording studio on Wednesday afternoon, and we have to say, good looks run in the family! The 19-year-old starlet covered up her cropped locks with a black beanie, but she showed off her slim waist in a super short skirt and a cropped black tank. Tish rocked a pair of skinnies and this season's must-have Isabel Marant booties ... you know Miley's gonna swipe those at some point if she hasn't already!

Yesterday Miley tweeted a picture of a text from her makeup artist Pati Prema Dubroff referencing her upcoming Cosmopolitan shoot, and she later wrote, "Not sure if I was supposed to drop that [bomb] yet haha! <3 Pix look soooo dope!" Cosmo confirmed the upcoming cover and tweeted, "The rumors are true: Yes, we just shot @MileyCyrus for her first Cosmo cover. Yes, @RachelZoe was involved. Yes, the photos are UNREAL."

But when will we get our first peek?!

Robert Pattinson and Kristen Stewart attended the London premiere of The Twilight Saga: Breaking Dawn – Part 2 at the Odeon Leicester Square, and the lovebirds had everyone's attention as they posed for photos on the red carpet.

After nearly flashing her derriere on the red carpet at the Los Angeles premiere, Kristen wore another lacy Zuhair Murad design that left little to the imagination, and Rob looked smokin' hot in a Burberry suit. If K. Stew thought parading around in sexy outfits would get everyone to stop talking about her cheating scandal, mission accomplished!

But this glam look didn't last very long! After sitting through yet another screening of the film, Kristen wiggled out of her sexy jumpsuit and changed into jeans, sneakers and an army jacket:

Planning a gathering, Ms. Berry?!

Halle Berry and her fiance Olivier Martinez stopped by an LA store today to pick up party supplies, and we can't help but wonder who she's throwing the big bash for! It's not daughter Nahla's birthday, and it's not her hunky French beau's either, so maybe she's a room parent at school?

Celebrating something is the last thing we expected the Dark Tide actress to be doing, considering she just lost her huge custody battle with ex Gabriel Aubry! The judge ruled that the 46-year-old will not be able to permanently move to France with her daughter, as it would impede regular visitation with the Canadian model.

We guess she could be throwing a "Staying in L.A" fete!

Rihanna took off today on her 777 Tour, which has her visiting 7 countries in 7 days in a chartered plane full of her most dedicated fans and a handful of journalists. The group is off to Mexico City right now, and over the course of the next week they will make stops in Toronto, Stockholm, Paris, Berlin, London and New York.

"You guys ready? 77 motherf*cking 7! Ready for Mexico? Ready for some tequila? Let’s get drunk!” Rihanna said over the loudspeaker as soon as everyone boarded the jet. “Everybody look in their gift bags right now. There’s a string in there that looks sh*tty and cheap. But it’s a real diamond!!! I don’t want you guys to lose that. You can never say you’ve never has a diamond in your life. Give it to someone special. I love you."

MTV reports that the 24-year-old singer is performing in venues that are a bit smaller than the sold-out areas she's used to, but not much is known about the concerts. Guess we'll have to wait and see ... you know RiRi will be giving us constant updates and pics on Twitter!
