Christina Aguilera, Pitbull, Florida Georgia Line and Nelly to perform on 'Voice' finale

Christina Aguilera, Pitbull, Florida Georgia Line and Nelly are to perform on next week's season finale of "The Voice" in Los Angeles, NBC said.

The 2-hour June 18 season-ender will also feature Bruno Mars in a special pre-taped performance of his newest single, "Treasure."

Mars recorded this performance last month before the recent unexpected death of his mother.

Cher, who will also participate, was previously announced.
