Christina Aguilera's featured guests in her new album "Light & Darkness" have been revealed. According to producer Christopher "Tricky" Stewart, Flo Rida and Santogold will lend their vocal to the effort.

"I know that there's a lot of other cool features, like I know that she has Santigold and Flo Rida on there," the powerhouse music maker told Rap-Up. Prior to that, he confirmed that Christina will also join forces with M.I.A.

The album has been finished and is currently on the process of mixing, but it will not arrive until next year. "She's gonna do the film [Burlesque] first. She didn't want to not be able to promote this record because it's gonna be a big record for her," Tricky said.

"The album is finished. She's mixing. She hasn't made a final decision about what the first single is, but I know everyone feels good about their options."
