At a British charity auction over the weekend, Rolling Stones guitarist Ronnie Wood bought a dinner date with Scarlett Johansson for $41,000.

He actually got into a bidding war with another guy for it, and in the end, even though Ronnie won, the two men decided to SPLIT the cost.

The money goes to breast cancer research.

( says it was $20,000 and the New York Post says it was $41,000. I'm going with the more reliable Post. Either way, he paid a BUNCH of money for the date.
