O.M.G.: Blake Lively and Penn Badgley have decided to end their three-year relationship.
A rep for the Gossip Girl co-stars confirmed the break-up to Us Weekly. The young stars officially ended things in mid-September.
While the hot pair may have ended things in mid-September, they were spotted getting pretty close (and kissy) on the Gossip Girl set on October 21 and September 25.
It's been a rough year for Gossip Girl off-screen romance. Co-stars Ed Westwick and Jessica Szohr called off their off-screen romance in April and Leighton Meester and Sebastian Stan broke up shortly after Ed and Jessica's romance fizzled.
Blake and Penn began dating in 2007. The pair first met as childhood classmates in California.
According to Us, no one on the Gossip Girl set had any idea that the "It" couple had ended their relationship. "Nobody on set had any idea," the insider told Us, "They're really just private."
