Robert Pattinson arrived at Jimmy Kimmel Live! in Hollywood on Wednesday afternoon, and the British hunk flashed a quick smile (and peace sign!) before heading in to the studio.

Since the news broke that longtime love Kristen Stewart cheated on Rob with her married Snow White And The Huntsman director Rupert Sanders, the actress has been laying low, but Rob has been forced to cope as best as he can while promoting his new flick, Cosmopolis. Despite a few awkward moments during interviews, Rob seems to be moving on, and now it's being reported that Leonardo DiCaprio has reached out to the 26-year-old actor, inviting him on an upcoming vacation!

A source told Showbiz Spy, "Leo has been one of Rob's role models for years, and Rob was totally taken by surprise when [he] called him. He invited Rob along on a getaway he's planning when he's in Puerto Rico for the wrap party on the movie he's producing, Runner, Runner. Leo wants to book a mansion at a secret location on the coast so he and his pals can party in private."

The insider added, "Leo figured it would be great for him to hang out with a bunch of laid-back guys. Leo joked they could compare baseball cap collections - and told Rob before he knew it, he'd be dating a model, just like him!"

Emma Roberts went on a coffee run while taking a break from filming We're The Millers in Wilmington, North Carolina.

The 21-year-old actress rocked A|X Armani Exchange Coated Legging Jeans while juggling three drinks after leaving a coffee shop. Looks like her tiny hands couldn't handle carrying all three beverages at once.

Good thing she didn't splash any on her cute outfit. Whew!

Does this mean it's baby time?

Reese Witherspoon was taken to a local LA hospital today, Radar reports.

"Reese was actually taken to the hospital on Tuesday night with complications. She was released that night and then rushed back to the hospital today. At this point it looks like she might have the baby," a source told the website.

The 36-year-old was rumored to be due in September, so it looks as if the Oscar winner might be going into labor earlier than expected, which is a bit of a concern for the actress and hubby Jim Toth.

"Reese and Jim are a little worried about having the baby so early. But it's close enough to her due date that they're confident the baby will be just fine," the source adds.

Looks like the stork couldn't wait!

We're not quite sure what's going on with the Black Swan beauty, but we'll just chalk it up to a bad hair/face day!

Today Mila Kunis was spotted leaving the gym in the valley on Wednesday, and the 29-year-old starlet looked nothing like the sexy brunette we remember from That 70s Show. Speaking of rolls roles, it was just announced that Mila will be joining the cast of Paul Haggis's drama Third Person with James Franco and Casey Affleck.

The flick follows three interlocking love stories, and Liam Neeson and Olivia Wilde are also set to star. Wonder who Mila is going to be paired up with? Hopefully boyfriend Ashton Kutcher won't mind her getting busy with someone else on the big screen!

Vanessa Hudgens and her pal Kim Hidalgo went shopping in Studio City on Tuesday afternoon, and while Vanessa covered up in a floral sundress, her BFF showed off her figure in a cropped top and a sheer maxi skirt.

Speaking of showing some skin, Vanessa's new trailer for The Frozen Ground has hit the web, and in the film she plays a stripper who is the target of a serial killer. The film also stars Nicolas Cage, 50 Cent and John Cusack, and it's based on actual events. The trailer has since been removed from several websites, but we have a feeling the official one will be popping up any day now!

Whitney Houston's daughter Bobbi Kristina has added yet another tattoo to her body.

This time, the aspiring 19-year-old singer has inked a musical note onto her ribcage. Bobbi, who was photographed with her boyfriend, posted the following:

Every single one of my tattoos are a symbol to me. Something that will mean something forever to me. Never meaningless, always meaningful (:

Just last month, Bobbi and her boyfriend showed off their wrist tattoos.

Where was she!?

Last night John Mayer dined at Loteria Grill in Hollywood, and rather than bringing his busty babe of a girlfriend, the 34-year-old singer rolled with several friends. While we're sure all is well with the hot new couple, there's a rumor circulating on the web that John is chasing after Katy in an attempt to get closer to her BFF Rihanna.

“They really hit it off,” a source tells the National Enquirer of one of their first meetings at a 2009 music industry party in New York. “John was smitten. He tried to lure her back to his place on several occasions, but Rihanna just laughed him off, saying she wasn’t his type. That only made him want her more ... Rihanna has ALWAYS been a fantasy chick for John.”

“Katy has no idea just how hard he tried to score with Rihanna,” another source added. “Now, her pals are worried she’s headed for heartache.” Yikes! We doubt that's true, but will Katy's romance with the serial dater last?
