Everyone from teen heartthrob Joe Jonas to TRON hottie Olivia Wilde (not sure about that dress though!) attended the W Magazine Golden Globes Best Performances Issue party in West Hollywood last night, and it looks like all the A-listers are ready for a star-studded awards ceremony this Sunday evening.

Last night Rumer Willis was snapped leaving the Nine Zero One salon in West Hollywood with much redder hair, and we're not sure how we feel about it! Maybe she's looking to transition to a blonde 'do? That could be fun!

Nicki Minaj has set the record straight on rumors that she's reportedly shacking up with Rihanna. "I don't know where people got this really insane, hilarious, random rumor that she and I were living together," she said on a radio show this week.

Nicki continues, "We had just shot the video for a song I have on the album called Fly. When I saw her the first thing I said was 'So, did you hear we're living together?' We just started cracking up laughing and she was like, 'I can't believe people are this ridiculous.'"

Rumors began to circulate that Minaj and Rihanna were more than friends when the girls posted sexy pictures on Twitter, writing captions like, "Me and Nikki in our new crib, lol! Getting busy on set of FLY!! Its so hard to keep my hands off!" Minaj responded, saying, "If we're gonna liv 2gthr and hook up u gotta learn how 2 spell my name!"

Minaj added, "People still didn't realize we were joking. People were still hitting me saying, 'Oh my god, you're so lucky. You and Rihanna?' You can't even be sarcastic anymore. It was hilarious though."

In other news, Nicki will appear as a musical guest on Saturday Night Live on January 29.

Spotted: Oscar winner Sandra Bullock touching down at Los Angeles International airport on Friday evening, rocking a cute and chic outfit. How it is that her hair looks this good just minutes after stepping off a plane, we'll never know, but more power to her!

After Usher bailed out of a rescheduled Berlin show on Wednesday evening, the R&B star has now cancelled this weekend's concerts in Holland, Germany and Belgium, due to a respiratory illness.

Usher's rep released the following statement on the matter:

"Usher is suffering from an upper respiratory illness which is currently preventing him from performing a proper show. After consultation with doctors, he has been advised to reschedule the upcoming dates in order to get the rest he needs to ensure a complete recovery."

Usher was quoted as saying, "I have been very excited about my European tour and I deeply regret having to reschedule the shows. I am truly sorry for any inconvenience I have caused my fans. My fans are the best in the world and I am looking forward to getting better so that I can give them the show they deserve."

According to his management, Usher wasn't "feeling well" on Wednesday, and after singing just five songs and getting booed by the audience, he left the stage. The singer is due to kick off the UK leg of his world tour in Manchester on January 26, so hopefully he'll be recovered by then!

He just can't tame his inner douchebag!

Britney Spears' latest single "Hold It Against Me" has held the number one spot on iTunes since its midnight debut on Tuesday, and Kanye West made it clear that he wasn't thrilled about it, tweeting, "Yo Britney, I'm really happy for you and I'mma let you be #1, but me and Jay-Z's single ["H.A.M."] is one of the best songs of all time! LOL." LOL? Not so much.

West later removed the tweet and apologized, saying, "On a serious note I'm truly happy for Avril Lavigne and Britney Spears. No hate in 2011...I thought LOL signified a joke." Still, Spears' manager Adam Leber sarcastically quipped, "Thanks for 'letting' us be #1. Much appreciated."

As you know, this isn't the first time the unpredictable rapper has caused drama with the pop princess -- back in 2007 he reportedly had a meltdown backstage at the MTV Video Music Awards when Brit Brit replaced him as the show's opening performer.

Last night Tom Cruise and wife Katie Holmes were snapped leaving the Chateau Marmont, and the Hollywood supercouple hid in the back seat of a chauffeured car on the way out. Aww, what happened to the days when these two would ride around on a motorcycle and proclaim their love for one another? We kinda miss the TomKat mayhem of last decade...

An adoring boyfriend, a Golden Globe nomination, a perfect size 2 figure and on top of all that, she's loading up at a posh gifting suite!

The starlet and her main squeeze Alex Beh were snapped leaving the GBK Golden Globes Gift Lounge at the London Hotel on Friday afternoon, and clearly life is good for the brunette bombshell and it shows. Take that, Jamie Kennedy!
