For his December 7th release No Mercy, T.I. has nabbed none other than Christina Aguilera for the closer "Castle Walls":
Christina, T.I., & producer Alex Da Kid did a very nice job with this one! While we're on the topic of Christina & speaking of being impressed, I saw "Burlesque" last night & LOVED it! Honestly, the movie was a joy to watch & each & every musical number was a showstopper! I highly recommend it.
