Penn Badgley Blake Lively Breakup

It’s all over between Gossip Girl lovers Penn Badgley and Blake Lively.

A rep for the show confirms that the stylish pair ended their three-year relationship in September. An insider tells Us Weekly Magazine that despite their parting of the ways, the ever-leggy Lively, 23, and Badgley, 24, have remained “professional” on-set and maintain an amicable relationship.

“They’re professionals. They’re still good friends and hang out on the set. They kept this news to themselves for a while. Nobody on set had any idea. They’re really just private.”

Penn and Blake began dating after meeting on the set of Gossip Girl in 2007. In an interview Men’s Health last November, Penn spoke fondly of the romance with his co-star — even if workplace romances are frowned upon.

“Having a relationship with someone you work with might not always be the smartest move, but, it’s been wonderful to be in a relationship where we can both identify with what the other is experiencing.”
