Yes, Chace Crawford has definitely seen Carrie Underwood nude by now.
But that's not the only exciting news emanating from the cast of Gossip Girl.
Another star of The CW show, Blake Lively, appeared on Live with Regis and Kelly earlier in the week.
Seen here, she took time to sign autographs outside studio, before spending most of her segment discussing her unique shows with Kelly Ripa, who insisted on trying one on.
Blake Lively is a popular new star. But will she go the way of sweet Hayden Panettiere or dirty Lindsay Lohan?
