The pic was revealed yesterday, when Jake appeared on The Late Show with David Letterman to chat about working with Anne in their new film Love and Other Drugs, in which she often gets naked.
When asked what it was like to film sex scenes with his co-star, Jake joked: "I mean, look. I've had a pretty illustrious career at this point but the hardest thing has been pretending to be turned on by Anne Hathaway" .
Those keen to see the fruits of his labour will have to wait until December 31, when Love and Other Drugs is released in the UK. But in the meantime, you can get the scoop by watching Jake's interview with David Letterman in video below.
