T.I. is continuing his run on the media circuit, promoting his recently released book Power & Beauty as well as his upcoming reality show. He previously showed up on The View and Howard Stern, and most recently appeared on Chelsea Lately’s late night program.

About the book, which is inspired by Sister Souljah’s 1999 novel The Coldest Winter Ever, he described, “It’s a fictional story about two teenagers that are thrust into adult situations…they actually have real life circumstances to navigate themselves through. Power [the main character], he’s being mentored by a gentleman that is taking him down a path that most teenage boys need to stay away from. After their guardian dies, that’s who takes them in.”

The interview, however, was mostly filled with jest, as T.I. even poked fun at Lately’s rumored past relationship with rapper 50 Cent.

“Your last name isn’t ‘Lately’ by the way, Chelsea,” T.I. said.  “I thought your last name was ‘Cent.’ I thought it was Chelsea Cent.”

Lately responded, “No that’s not true, 50’s last name was ‘Lately’ for a while. But then we changed it back.”

T.I.’s Power & Beauty released on October 18, and his VH1 television show will begin on December 5.
