Kardashian sisters in gay rights campaign

Kim, Kourtney and Khloe Kardashian have covered their mouths to promote a new gay rights initiative.

The three sisters, who appear in the E! reality show Keeping Up With The Kardashians, lent their taped-up faces to the NOH8 campaign.

The campaign's goal is to get rid of discrimination against homosexuals in the US.

Kim, 28, said: "I believe everyone should have the right to choose who they marry and that we do have the power to make a difference."
