Bruce Willis' daughter Rumer Willis helped to raise $12,000 (Gbp7,500) for a gay and lesbian charity event on Sunday (11May14) by offering up a date to the highest bidder.

The 25 year old made the spontaneous gesture at the Los Angeles Gay & Lesbian Center’s 2014 An Evening with Women fundraiser, which was hosted by newlywed lesbian rocker Linda Perry.

This year's (14) event raised $600,000 (Gbp375,000) and featured performances from actresses Milla Jovovich and Evan Rachel Wood.

Perry also reunited her former band 4 Non Blondes for the first time in more than 20 years for the event.
