Matt LeBlanc attends the 2016 CBS Upfront at The Plaza on May 18, 2016 in New York City. Jemal Countess/Getty Images Matt LeBlanc gave a surprising answer when Lady Gaga had him choose between two ?Friends? characters. While on the ?Late Late Show With James Corden? on Tuesday, the 49-year-old actor -- who portrayed Joey Tribbiani on the beloved sitcom -- was asked by the 30-year-old pop star: ?Who?d you rather: Monica or Rachel?? Corden and Jeffrey Dean Morgan -- who was also a guest on the CBS late-night show -- went wild for that answer and Gaga also approved.
