Robert Pattinson has learned his lips are worth a staggering $20,000 - after a kiss with the actor was auctioned off at a charity event on Thursday.

The Twilight actor offered up his smooch at a gala for the American Foundation for AIDS Research, a fundraiser held at the Cannes Film Festival every year.

The star blushed as he was introduced by movie mogul Harvey Weinstein, who told the crowd they were bidding for a chance to meet, greet and receive a kiss on the cheek from the hunky Brit.

Pattinson joked, "If it goes well, maybe it will turn to something more!"

The bidding jumped to a staggering $20,000, with two lucky guests winning the final prize.

Hollywood couple Joshua Jackson and Diane Kruger also auctioned off a Segway vehicle, while a saxophone donated by former U.S. President Bill Clinton went for $130,000.
