Rumer Willis auctioned off Jayson Blair for charity.

The 24-year-old actress spontaneously offered up a date with her 'The New Normal' star boyfriend of one year at a fundraiser for Direct Relief in Santa Monica to help raise money for the charity, which provides medicine and medical equipment to people in need around the world.

A source told gossip website ''It was totally spontaneous.''

Acclaimed chef Frank Ostini, owner of the Hitching Post II restaurant in Santa Barbara's Santa Ynez Valley, which featured in the movie 'Sideway' - eventually secured the date with the 29-year-old actor after bidding $3,000 and invited Rumer to join them for dinner at his hugely popular establishment.

The fundraiser was held at the home of top entertainment lawyer Jeanne Newman and her husband, 20th Century Fox Television Chairman Gary Newman, and raised $250,000 for Direct Relief.

Jayson and Rumer's relationship is increasingly serious and he joined her and her family, including her father Bruce Willis and his wife Emma Hemming, at her sister Scout's graduation from Brown University late last month.

Her mother Demi Moore was not present.
