Bow Wow and Christina Aguilera are joining forces, but it’s not for new music.

After announcing his RETIREMENT from rap, Shad Moss is linking up with Christina Aguilera for “Tracks,” a new music-based game show set to premiere with back-to-back episodes Sept. 1 on SPIKE, the network that also produces “Lip Sync Battle.”

Hosted by Bow and executive produced by Aguilera, the show will feature teams trying to name a tune based only on portions of the “Tracks.”

“It’s like a live concert where a game show breaks out,” said Bow Wow in a trailer.

Other celebrity guests, including Tommy Lee, will also join in on the fun. Lee is set to play the drums in one of the upcoming episodes while Christina will appear in at least two.
