Gossip Girl stars Penn Badgley and Blake Lively have publicly endorsed Barack Obama’s campaign for President.

The young lovers are just a pair of young people featured in a new public service announcement encouraging teens to “Talk To Their Parents About The Dangers of Voting Republican.”

Spoofing the old 80s’ “Say No To Drugs” campaign.

“Just because other people your age are doing it, doesn’t make it cool,” says one actor

“And if you’re ever out somewhere and you’re considering voting McCain, just call me. I’ll pick you up. No questions asked,” Blake pleaded.

Broadway’s long-running musical Rent went out with a bang earlier this month when theatre-goers were treated to an impromptu showdown drama between real-life Gossip Girl lovers Blake Lively and Penn Badgley outside the show’s final performance at Nederlander Theatre.

The young lovers have reportedly come to an impasse in their relationship, caused by Penn’s alleged bitterness over Blake’s rising notoriety.

“It was the same old argument — Penn’s sick of living in Blake’s shadow. He often feels like her ‘manbag’ when they go out. Things came to a head between them.”

The cast and crew of The CW’s Gossip Girl want co-stars and real-life lovers Penn Badgley and Blake Lively to get a room.

The lovebirds have been consistently spotted kissing and smooching as the show shoots scenes for its second season on location in New York City-and all the public displays of affection are beginning to make everyone else around them nauseous.

“It’s gotten crazy, they are all over each other after every single take,” a spywitness told the New York Post Monday. “They’re constantly making out, and it’s making everyone uncomfortable.” Our spy tells us that Badgley also has a new love interest on the show, who seemed to make Lively a little “nervous.” “He’s in scenes with this new cute brunette, and Blake is all over him after wards. And no one on set is talking to the new girl be cause they don’t want to upset Blake.”
