90210 newcomer Freddie Smith, who plays Marco, the current romantic interest of Trevor Donovan's gay character on the nighttime teenage drama, has posed for the NOH8 Campaign, which raises awareness and funds to end Proposition 8, California's gay marriage ban.

The NOH8 Campaign, which is helmed by photographer-activist Adam Bouska and his partner Jeff Parshley, photographs celebrities and everyday folks with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

In a recent interview with gay male entertainment website AfterElton.com, Smith explained how he became involved in the campaign.

“My publicist called me and told me about the NOH8 Campaign and I said absolutely and I did a photo shoot,” Smith said. “I'm still really excited to see how it all turned out and it's a great campaign and the guy doing it was super nice and I was happy to be a part of it.”

The campaign received a huge boost in January when NCIS star Pauley Perrette wore a strapless dress that featured the NOH8 Campaign's logo to the People's Choice Awards in Los Angeles.
