Nicole Richie made her fashion presence known during Fashion's Night Out at The Beverly Center.

While speaking to a room full of spectators, the House of Harlow 1960 designer sported several pieces from her line ... all at once! That's one way to show off your goods.

Richie, 29, is currently filming her upcoming reality show Fashion Star alongside Jessica Simpson. As for the reported feud between the two designers, Nicole told Ryan Seacrest that the story "couldn't be further from the truth."

Nicole Scherzinger definitely has the X Factor.

The former Pussycat Doll made an appearance at a Fashion Night Out event on Melrose Place in West Hollywood Thursday night, and the sultry star was decked out in an eye-catching gold suit.

The X Factor host belted out a few tunes at the Oscar de la Renta event, before enjoying the lavish party with friends.

We can't wait to see Scherzinger bring her sassiness to the upcoming X Factor!

Rihanna is looking hardcore in the latest campaign for Armani Jeans ... bleached blonde hair and all!

The 23-year-old stunner, snapped by celebrity photographer Steven Klein, sports tight jeans, black boots and a cropped top exposing her toned tummy. And in a second shot, Rihanna lost the jeans all together. We're not complaining.

Seems as though RiRi can pull off just about any look!

Dressed to the nines in a body hugging Herve Leger dress and sky high Christian Louboutin heels, Billion heiress Tamara Ecclestone arrived at club Voyeur in Hollywood to meet up with new pal Brody Jenner Thursday night.

The Formula 1 heiress and her younger sister, Petra Ecclestone, have been making a splash in LA ever since newlywed Petra purchased Candy Spelling's mansion for $85 million, last June. It appears the sisters have been taking over the Hollywood scene ever since.

Do we hear a reality show coming soon?

Eva Longoria and Mario Lopez make such a cute couple, even if the two hotties are just close friends.

While Mario took care of his hosting duties for Extra at The Grove, his BFF Eva stopped by for a few good laughs and to show off her adorable yellow dress.

The sexy Desperate Housewives star has been dating beau Eduardo Cruz for the past nine months, but as we reported yesterday, Eva is not engaged ... yet. We have a feeling Mario knows Eva's relationship secrets.

We'll be watching to see if Eduardo ends up putting a ring on it!

Chris Brown looked anxious to jet out of LA, as he made his way to the terminal at LAX with trusty bright red skateboard in hand, on Thursday night.

The "FAME" singer recently had a bit of luck when he was cleared of $15,000 worth of parking tickets by the City of West Hollywood.

Brown racked up a whopping 117 tickets for parking in the handicapped spot at his condominium complex, but fortunately for the singer, only 22 citations now remain open.

Ashton Kutcher, Jon Cryer and Angus T. Jones are busy rehearsing for their upcoming show Two and a Half Men, but it didn't stop the cast from appearing via satellite on The Late Show With David Letterman to deliver the coveted Top Ten List.

Ashton gave out the #1 reason to watch the new season. He said, "Watch it, don’t watch it. I get paid either way.”

After the cast finish their brief and lackluster appearance, Letterman joked, "I think they were under the impression that this was a rehearsal."

What do you think? Did the three guys REALLY seem happy to be there?

The new season premieres on September 19.

Considering he became a self-made millionaire at the tender age of 14, we're not too shocked to hear Justin Bieber has no plans to attend college.

The Baby singer stepped out for Fashion’s Night Out on Thursday night, and when several reporters asked if we has panning to hit the books after the high school, the 17-year-old replied:

“To be honest, not in my plans as of now.”

But won't he miss attending classes?

“No actually, I really don’t. [High school] is so dramatic. I hate drama,”Bieber confessed.

All that Hollywood drama must be enough for one kid to handle!
