T.I. recently stopped through "Chelsea Lately" to dish on his new novel, Power & Beauty, while also ribbing the talk show host about her past relationship with 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."

Chelsea rolled with the punches, replying "No that's not true, 50's last name was 'Lately' for a while, but then we changed it back."
