T.I. Clowns Chelsea Handler

While appearing on "Chelsea Lately" to promote his recently-released book Power & Beauty, rapper T.I. decided to poke a little fun at host Chelsea Handler and her past with hip hop superstar 50 Cent. T.I. joked that the late night host had changed her last name.

"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."

"No that's not true, 50's last name was 'Lately' for a while," Chelsea quipped back. "But then we changed it back."
