The YBF crowd may not have been out in full force at tonight's 2012 Billboard Music Awards, but those who hit the white carpet looked fab indeed.  Check out pics of Brandy looking stunning, Mr. & Mrs. Beatz, Wiz Khalifa & his fiancee Amber Rose, Jordin Sparks and more inside...

B Rocka stunned the white carpet at the MGM Grand Garden Arena in Las Vegas tonight (May 20) in a nude pleated & fringed plunging Herve Leger by Max Azria mini dress.  With a head full of curls--that we're drooling over--and perfect dramatic makeup, the singer/actress looked fabulous:

Great choice of gold bow embellished Christian Louboutin 'Lady Peep' slingbacks.

Brandy was on hand to introduce her "Put It Down" collabo partner, Chris Brown, before he took the stage to perform.

Also keeping with the nude trend, pretty girl Jordin Sparks lit up the carpet in a lace scalloped hem curve hugging dress by Diane von Furstenberg as she hit the carpet ahead of her tribute to co-star and idol Whitney Houston.  The Sparkle star will be performing her late co-star's signature song "I Will Always Love You," while new "Duets" star John Legend will perform "Greatest Love of All".  And Bobbi Kris will accept the Millennium Award on her mother's behalf.

Of the plans, Co-Executive Producer of the show, Richard Beckman, said, "I was at the Grammys, and what a curveball they were thrown when Whitney passed away [the day before the show]. They did a good job with Jennifer Hudson, but obviously we had a bit more time, so we wanted to do something honoring such a remarkable performer. We have a lovely segment with a full orchestra and John Legend doing "The Greatest Love of All" -- his voice is just smashing -- and Whitney's last co-star [in the movie "Sparkle"], Jordin Sparks, "Doing I Will Always Love You." And Bobbi Kristina, Whitney's daughter, will accept the Millennium Award for her mother, which we created last year for Beyonce -- that's probably the highest tribute we could pay."

And with her signature smile, the singer/actress hit the carpet solo and with her boo (who's not rocking his neck brace for the first time publicly) Jason Derulo:

Cute!

And speaking of John Legend, he and his model fiancee' Chissy Tiegen hit the carpet looking so in love:

Interesting red cocktail dress for Chrissy.

Swizz Beatz & Alicia Keys stuck to their black & white theme for tonight's Awards:

Swizzy kept it extra clean in an all white suit, while Alicia flossed her mommy curves and tons of earrings in this snug black long sleeved Azzedine Alaia Couture gown:

Not feeling this huge braid in the front, but the dress is perfectly flattering for her.  She will also be performing tonight alongside Stevie Wonder.

Meanwhile, Amber Rose rocked her usual white strapless mini dress I feel like we've seen plenty of times on her before.  But she knows the color works well for her.  Paired with a gold pumps and bright yelow nails, the "model" was on the arm of her fiance Wiz Khalifa, who won one award (so far) for Top New Artist.  And, of course, he gave his proud lady a shout out during his acceptance speech.

Somebody played a little too long in the body glitter.

In addition to winning an award tonight, he also presented an award to LMFAO.  Congrats Wiz. 

Usher made sure he wasn't missed on the carpet in this bright sky blue suit.  And surprisingly, we kinda love it.  He hit the stage to perform his track "Scream".

And LMFAO are racking up tonight.  They've won 2 awards so far: Their "Party Rock Anthem" won for Hot 100 Song of the Year and the twosome won for Top Duo/Group.

Miguel brought his girlfriend on the carpet in this mesh outfit.  Feels like she thought if she threw on the Unbout Louboutin with this dress..we wouldn't think it was from Rainbow.  But we still do.

Also at the Awards--Monica & Eric Benet presented the Top R&B Artist Award.

Mo and her hubby Shannon Brown tweeted pics together and with Chris Brown at the show while Mo said: “Congrats to @chrisbrown R&B Artist of the yer #BBMA”

Stay tuned for more pics!
