blake livelyBlake Lively and Penn Badgley’s off-screen romance is reportedly causing problems on the set of their show Gossip Girl.

An inside source told the New York Post: “It’s gotten crazy, they are all over each other after every single take.

“They’re constantly making out, and it’s making everyone uncomfortable.”

The source added that the new heightened levels of affection may be Blake’s way of fending off the competition: “[Penn]’s in scenes with this new cute brunette, and Blake is all over him afterwards.

“And no one on set is talking to the new girl because they don’t want to upset Blake.”
