On Sunday, the who's who in Hollywood celebrated music's biggest night at the 2013 Grammy Awards in Los Angeles.  While some stars made headlines for breaking the Grammys' anti-skin exposure dress code others, like Justin Timberlake, were praised for delivering riveting performances at the packed out Staples Center.

Timberlake performed his new song "Suit and Tie" with hip hop mogul Jay-Z before going on to sing his new song "Pusher Love Girl" from his album "The 20/20 Experience" which drops on March 19.   No one was more proud of the "SexyBack" singer than his wife actress/model Jessica Biel who shared one the 55th Grammys' most memorable moments with superstar singer Beyonce.  Biel and Timberlake sat front row at the music award show next to Mr. and Mrs. Shawn "Jay-Z" Carter.  As Biel and Timberlake held hands, a photo caught Biel sharing a laugh with the "Single Ladies" singer which can be seen at the Huffington Post.

After the show, Timberlake performed a mini-concerted at a sold-out show at Hollywood's Palladium theater.  Sources say that the newly wed "7th Heaven" actress was beaming with joy throughout the "Suit and Tie" singer's performance.  She traded in her who traded her floor-length, black one-shouldered Oscar de la Renta Grammys gown for a knee-length red dress and was "in a great mood and super excited for the show," according to a source at Us Weekly. Even before her husband took the stage, she was "bopping around" the exclusive VIP-VIP section with her mother-in-law, Lynn Harless.
