Looks like Blake Lively and Penn Badgley have followed in their "Gossip Girl" characters' footsteps -- and have called it quits on their three-year relationship.
The duo, who still co-star together on the CW show, broke up mid-September according to Us Magazine -- which is right around the time they were spotted kissing each other on set.
The magazine says a rep for the couple confirmed the break-up.
