London, Nov 20 Kim Kardashian and her sisters-Kourtney and Khloe-have taped up their mouths for a new gay rights initiative.

The sisters each have lent their gagged faces to NOH8 - pronounced 'no hate' - which aims to eradicate discrimination against homosexuals in the US.

And Kim has said that she feels so strongly about equal rights that she didn't hesitate to sign up for the campaign.

"I believe everyone should have the right to choose who they marry and that we do have the power to make a difference," the Sun quoted Kim as saying.

The imagery is meant to take a dig at homophobic Americans, so that they think twice before opening their mouths with hate-fuelled outpourings.

However, the equality drive includes all couples who are the victims of prejudice.
