Posted on Mon May 2nd, 2011 2:55pm PDT By X17 Staff

Sean Penn, one of Hollywood's original bad boys, caused problems at the annual White House Correspondents Dinner over the weekend, the New York Post reports.

Penn supposedly raised eyebrows when he refused to put his hand over his heart for "The Star-Spangled Banner."

Then Penn and girlfriend Scarlett Johansson got too close for comfort at the formal dinner. A witness told the Post:

"She plopped down in his lap, and they were kissing."

Sources also said that the two left the room for an hour, after which Penn came back to their table looking disheveled.

The pair held hands as they left an afterparty in early morning hours.

See who else was at the dinner to witness the canoodling after the jump!

Saturday Night Live's Seth Meyers hosted the annual dinner which, as tradition demands, was quite the snarky evening. One of Meyers' zingers, for example: "Jon Hamm looks the way every Republican thinks they look," he said. "Zach Galifianakis is also here. Zack Galifianakis looks the way every Republican thinks every Democrat looks."
