George Clooney is auctioning off a lunch date with himself to raise money for America's Gay, Lesbian and Straight Education Network (Glsen).

The Hollywood hunk will entertain the lucky winner and a friend in an intimate lunch with entertainment writer David Karger at Soho House in West Hollywood.

The dinner date with the Ocean's Eleven star has been valued at $20,000 (£12,500) and will be up for auction until 11 October (12) on the CharityBuzz website.

The actor has long been a vocal supporter of the gay community and supports Glsen, which works to ensure safe and supportive schooling environments for lesbian, gay, bisexual and transgender youth.
