After doing dinner with Taylor Swift at Giorgio Baldi in Santa Monica, Rihanna changed her outfit (but not her blonde wig) and stopped by MyStudio in Hollywood at 1:40am.

The 24-year-old R&B hottie left with several friends just twenty minutes later, and we're not sure why, but we're guessing she got wind of the fact that ex-boyfriend Chris Brown and ladylove Karrueche Tran were just a few doors down at SupperClub on Hollywood Blvd. Chris, who appeared to be in a great mood, left the hotspot with Karrueche and all of her friends, and he even stopped to purchase a bouquet of roses for his main squeeze on the way out.

Rihanna probably would have flipped if she saw this going down -- good thing she left early and avoided a confrontation!

We already knew she was one tough mama, but this leather motorcycle jacket is definitely a departure from the frumpy sweaters and baggy tunics!

Of course, Jennifer Garner is still wearing her signature post-pregnancy mom jeans, but did we really expect her to lose the baby weight just three months after giving birth to her son Samuel?

These two are still together after all!

Selena Gomez has been busy filming two movies over the last month (Spring Breakers in Florida and The Getaway in Bulgaria), but given how awkward things have been since Justin Bieber brought a random high school girl as his date to the Billboard Music Awards in Las Vegas last week, we were beginning to fear that they had broken up!

Apparently those oddball tweets and Facebook postings had nothing to do with their relationship, as Selena was greeted by her 18-year-old superstar boyfriend as soon as she touched down at LAX last night. Biebs was waiting in a chauffeured car for his ladylove, and he gave her a huge smooch when she hopped inside. Aww, it looks like absence really does make the heart grow fonder!

Yesterday Justin tweeted, "1 more rehearsal day today...then off to OSLO on monday, then #DieInYourArms out Tuesday ...then #24Days until #BELIEVE . Im ready." His Believe tour kicks off in late September and runs through late January, so if the couple were able to survive after a month apart, four months won't be so bad right? I mean, Selena probably has an open invite to join him on tour...

Jessica Alba may not be the most scandalous interesting actress in Hollywood, but she's definitely one of the best dressed!

The 31-year-old Fantastic Four hottie was snapped running errands in Beverly Hills on Friday, and she snazzed up an otherwise snoozy outfit with cute grey booties, coral pants and her fav new aqua sunglasses.

Not only is she a fashion icon, but this mother of two is also making a serious impact with The Honest Company, which she launched earlier this year. Jess spoke at the OC Walk to Remember luncheon on Wednesday, which helped to raise money for local organizations that support parents who have endured miscarriages, pregnancy loss or infant loss. Of course, the Honest Co. was a partner for the event, so we're glad to see Jess using her fame to help others!

Talk about an odd twosome!

Last night Rihanna and Taylor Swift met up at RiRi's fav restaurant, Giorgio Baldi, and while it appears as though the R&B bad girl has gone back to blonde, alas, it's just a wig. "blonde was just for the shoot! I'm still black," she tweeted. But what was she doing dining with T. Swizzle?

After her lovefest in Cannes with boyfriend Kanye West, Kim Kardashian is back in Los Angeles.

The reality TV starlet touched down late last night at LAX, and before she landed she tweeted, "I knew all of this traveling & no sleep would make me sick :-( gonna be a loooong flight home!" Think Kanye will be flying out to bring her some soup? At the very least he should have it delivered for her!

While she may be a bit under the weather, at least she has a good sense of humor about it! Kim tweeted the pic below and wrote, "This is how I caught @robkardashian & @scottdisick at the airport passed out sleeping! LOL."

Hmm, whose Bloody Mary is that?!

Jennifer Love Hewitt was all smiles when we caught her leaving a lunch meeting in Beverly Hills on Friday, and earlier in the day the 33-year-old actress tweeted, "I hope everyone has a great day! I have lots of meetings and work today but first yoga!...;)"

J. Love IS looking pretty fit, and heck, she might even be back down to a size two! We're guessing all that cardio she did to prep for her lingerie-clad character in The Client List has paid off ... now if only she had someone to appreciate it!

Thankfully the starlet has stopped talking about Adam Levine, but we wanna know who she's going to go after next. After all, she did tweet at Joe Jonas last month ... she's definitely on the prowl!

Oops she did it again!

After allegedly storming off the set of The X Factor on Thursday, Britney Spears reportedly walked off in the middle of auditions on Friday as well.

"After a very popular contestant finished, Brit stood up and immediately walked towards the tunnel where judges enter," a show source tells Us Weekly. "Her bodyguards [and entourage] jumped up and ran after her. She was moving fast ... It was odd." After "a little while" the 30-year-old pop star came back as if nothing had happened, but no one seems to know why she's been so moody since auditions started in Austin the other day!

After a "stripper" reportedly "butchered" Brit's song "Hold It Against Me" on Thursday, she stomped off and was absent for performances by no less than four contestants. Brit denied the reports on Friday, tweeting, "#Britneywalksoff??? LOL was just taking a little break people. I am having the BEST time!!!" Umm, that's an awfully long potty break Brit!
