LeAnn Rimes has posed for the NOH8 Campaign, which raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

Last year, the 29-year-old Rimes choked up during a performance dedicated to the memory of troubled gay teens who had been bullied to death.

The country music star joined the Gay Men's Chorus of Los Angeles' annual Christmas musical extravaganza titled Comfort & Joy. Rimes became emotional as she dedicated her final song to gay teens.

“It's really sad when people can't be themselves,” Rimes said before singing an emotional rendition of The Rose in a duet with the chorus.

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

Rimes is seen giving the peace sign from one hand positioned above her head while wearing little more than a towel in her photograph.
