T.I. is a busy man. The rapper and producer is not only releasing his own music, he's teaming up with some of pop's hottest talent. In the past few months alone, T.I. has worked with Lady Gaga, Cher Lloyd and Britney Spears. Which T.I. collabo do you like best?

Lady Gaga isn't afraid to experiment with her music -- even if it means treading in R&B territory. 'Jewels N' Drugs' is a Miley-esque banger that mixes T.I.'s smooth rapping skills with Gaga's crooning. As far as the lyrics go, well, we'll take Gaga's love over jewels any day.

Cher Lloyd's T.I. collaboration was a major hit this summer. The pint-sized singer told PopCrush that she chose T.I. to guest on 'I Wish' because of his fantastic ability to write lyrics. Just listening to the rapper sing about hooking Cher up with bling and telling her to make a wish makes it clear he was the right choice.

T.I. also has a guest appearance on Britney Spears' new album, 'Britney Jean.' The autotune-heavy 'Tik Tik Boom' is one of the dancier tracks on the project. The majority of the song is Brit seductively chanting, "Make me tik, tik, boom," so T.I.'s silky smooth voice is the perfect balance. The rapper's rapid-fire verse is all about, uh, lighting Britney's fuse and in the context of the song, we won't question it.

Which T.I. collabo is your fave? You can vote once an hour until the polls close on Monday, Jan. 6 at 4PM ET. Go, go, go!
