Didn’t get enough of Christina Aguilera in Burlesque over the weekend? You’re in luck.

The Bionic belter adds her golden pipes to rapper T.I.‘s new single, “Castle Walls,” from his upcoming album No Mercy (out on December 7). The track, produced by Alex Da Kid (who helmed the mixing board for Eminem and Rihanna’s two-part collaboration “Love the Way You Lie”), offers a classic “grass is always greener” message, cautioning that fame and fortune aren’t always all that their cracked up to be, with lyrics that read, in part,

“Everyone thinks that I have it all
 but it’s so empty living behind
 these castle walls.”

Give “Castle Walls” a listen below, and be sure to offer your opinions in the comments section.
