Usher and Alicia Keys are on the same line-up for the first time in a long time.

The former ‘My Boo’ duo have been announced as performers, along with Shakira, for this year’s NBA All-Star half-time show.

Usher, who took the Grammy stage to honor his musical idol Michael Jackson on Jan. 30, is set to sing his new song, ‘More,’ during the 2010 NBA All-Star players introduction. The ‘Confessions’ singer is a minority owner of the NBA team Cleveland Cavaliers.

TNT, which is airing the NBA All-Star festivities, will also show an exclusive music video with Usher for the single, which is now being shown in Regal Cinema movie theaters nationwide.

Meanwhile, Keys will sing three songs: ‘No One,’ ‘Empire State of Mine’ and ‘Try Sleeping With a Broken Heart.’
The 2010 NBA All-Star game will air Feb.14 at Cowboys Stadium in Arlington, Texas.
