"The Hills" star Lauren Conrad is doing her part to combat dating-related violence by working with Avon to donate profits from her beauty and accessories line, mark, to anti-violence groups.

"I have partnered with mark in its first initiative, aimed at ending the cycle of dating abuse and violence. Women ages 16-24 experience the highest rates of partner violence, and mark and I want to change that statistic," Conrad said. 

Avon says in a product listing that 100 percent of the net proceeds from Conrad's Have A Heart Necklace will be donated to the Girls M.powerment Campaign.

Conrad serves as the spokesperson for the campaign as well as the first Honorary Co-Chair of the M.powerment Expert Advisory Board.
