Scarlett Johansson 02.08 PtScarlett JohanssonScarlett Johansson has given a whole new meaning to the phrase "cheap date".

She’s certainly not that.

After auctioning herself off online, the buxom actress was bought yesterday on eBay...

For a staggering £20,000.

But before you think ScarJo has fallen upon hard times, you should know that it’s all for a charity event, raising money for one of Scarlett’s fave charities, Oxfam.

The lucky winner is an unnamed Brit, known only by his eBay nickname of Bossnour.

He gets to join the beautiful blonde for a mere 20 minutes at the world premiere of her new movie, He’s Just Not That In To You in July.

So as well as the jolly expensive date with Ms Johansson, Bossnour will have to fork out even more poundage for the airfare over the pond.

We wonder if she’ll invite him back to hers for coffee at the end of the night...
