Blake Lively's Ex Penn Badgley 'So Happy' for Newlyweds

Penn Badgley is in Toronto promoting his new film Greetings from Tim Buckley, but the news of his ex Blake Lively unexpectedly tying the knot with Ryan Reynolds in South Carolina traveled fast.

"I actually didn't know until last night, but I think it's fantastic," Badgley, who still costars on the CW show with Lively, tells PEOPLE. "I couldn't be happier for her."

"I'm so happy for her," continued Badgley, who learned of the wedding by reading reports and speaking to "people who are close to her."

Added the actor of his ex's relationship with Reynolds, 35: "I think it's everything that it should be."

Blake Lively Returns to Work on Set of Gossip Girl

Spotted: Newlywed Blake Lively getting back to work.

The actress returned to the New York City set of Gossip Girl on Monday – and was photographed talking on the phone in a jacket that appears to be hiding some seriously stylish Serena van der Woodsen duds.

Lively, 25, and Ryan Reynolds, 35, tied the knot Sept. 9 in a secret ceremony near Charleston, S.C., where they were spotted days later shopping and smiling by locals.


"They promised to support and love each other and to make each other laugh," a source told PEOPLE of their vows.

Taylor Momsen and Jessica Szohr to Leave Gossip Girl

There's going to be a shakeup on the Upper East Side!

Although Gossip Girl has been renewed for a fifth season, not all its fashionable characters will be back: Taylor Momsen, who plays Jenny Humphrey, and Jessica Szohr, who plays Vanessa Abrams, will not return as series regulars, PEOPLE can confirm.

The news may not come as a total shocker – Momsen, 17, hasn't appeared on many recent episodes, and in season 4 the character played by Szohr, 26, left town.

Still, both stars may make guest appearances in season 5 – and Momsen fans can check her out when she performs with her rock band, The Pretty Reckless.
