T.I. has teamed up with Dr. Dre on his forthcoming mixtape F**k Da City Up, and says that they created "great chemistry."

In addition to his family reality show with wife Tiny, Tip has been focusing on creating new music and is also working on a new album. However, if a legend such as Dre is featuring on his mixtape, fans can expect nothing short of amazing from Tip's forthcoming material.

"Dre was here. He sent for me over to the spot. We really just turned up more than anything else. It was about creating chemistry," he told MTV News.

"Of course we can get together, he got hot beats and I got dope rhymes, so we can always get together and make music. But for people to feel what we're sayin' and for it to sound like a party comin' through your speakers, you gonna have to create some chemistry."

He added: "So that's what we spent more time doin' than anything else; developing that chemistry."

Tip and Dre have previously worked together on a track titled 'Topless,' that was expected to feature on Dre's elusive Detox album, but was leaked online.
