Channing Tatum got a little too close with co-star Jonah Hill on the set of “21 Jump Street.”

Tatum, appearing on tonight’s episode of “The Tonight Show With Jay Leno,” discussed a scene in the movie involving a sprint down a highway. The scene took three days to shoot, so the film crew employed masseuses to keep the stars limber.

Hill was getting a massage, when Tatum took the masseuse’s place.

And Tatum dug in.

“It was amazing, the things he let me do to him before he realized that this wasn’t normal,” Tatum said. “I don’t know where he’s getting massages at.”

As this all was happening, cars continued driving past the film set – “and I’m sure that was a shock,” Tatum said.

“Happy ending on the highway,” Leno quipped.
