Talk about a being a good great friend.
Justin Timberlake was the surprise guest during his pal Timbaland's performance at last night's launch of the United Nations Foundation's new mobile initiative, mPowering Action, at the Conga Room in downtown Los Angeles.
J.T. joined Timbaland on stage to perform their hit "Carry Out" for an enthusiastic crowd of twentysomethings, including hottie Kellan Lutz, his Twilight costar Nikki Reed and her husband, Paul McDonald. Also in the audience were Timberlake's fellow 'NSync member Joey Fatone and his wife Kelly. (Fatone told me he and Timberlake talked a couple of weeks ago for their birthdays, which are just three days apart.)
Dressed in a white shirt, black sweater and jacket and a black ski cap, Timberlake ended the song with a shout-out to Timbaland before leaving the stage with smile and a simple, "See you on Sunday."
Timberlake is not only performing at the Grammys tomorrow, but also later in the night, he'll do the same at an after-party at the Palladium in Hollywood.
The 32-year-old singer recently released "Suit & Tie," the first single from his much-buzzed-about upcoming third solo album, The 20/20 Experience.
Also at the mPowering event were Timbaland's wife Monique Mosley, Estelle, Pharrell Williams, Cheryl Burke and Lamorne Morris.
