After numerous delays, it looks like Big Boi's upcoming album, "Sir Lucious Left Foot: The Son of Chico Dusty," will finally see the light of day -- on a new label. The rapper, one half of the collective Outkast with partner Andre 3000, announced via twitter on Friday (March 19) that he has signed a solo deal with Def Jam records. A rep for Def Jam has confirmed the announcement.

"BREAKING NEWS!!!! It's Official Big Boi signs solo album Deal with Def Jam!!!!! More details to come..." The Atlanta MC tweeted at 9:40 PM. "Ink is on paper," he posted just a minute later.

For the past three years, since first announcing work on the solo album, Big Boi has been releasing tracks from "Lucious" including Royal Flush," which features Andre 3000 and Raekwon; "Sumthin's Gotta Give" with Mary J. Blige; "Dubbz"; "Fo Yo Sorrows" with George Clinton and Too $hort; and most recently, "Shine Blockas" with Gucci Mane. Big Boi also told Billboard.com recently that he's worked with T.I., Lil Jon, Jamie Foxx and B.O.B. for the album, which was originally due at the end of 2008 via LaFace/Zomba. Big Boi currently appears on the remix to B.O.B.'s latest single, "Nothing On You."

"There's been a lot of stops and stars with this project," Boi told Billboard.com back in December. "I've just been trying to make sure we've got the right avenues and the right brains and mindsets together to get the marketing and promoting behind it. When you work on something for, like, two years and 11 months, it's like your baby. You want to make sure that everybody has taken the project the way they're supposed to be taking it and the set-up is right."
