G.I. Joe: Rise of Cobra star Channing Tatum will always be red faced when he bumps into co-star Sienna Miller - because he dropped her during an action scene.

The hunk lost his balance in a water sequence and the Brit slipped from his grip and slumped to the floor.

Embarrassed Tatum says, "The first take, the DP (director of photography) comes up to me and says, 'Whatever you do, don't drop her.' I never dropped anybody in my entire life and I dropped Sienna Miller. It was the worst, man."

But Miller insists it wasn't a big deal and now she can laugh about the day Tatum dropped her: "It wasn't his fault... There was water going off and everything and it went off early and got really slippery and we both slipped and he dropped me. He dropped me very heroically.

"He dropped me and then he rolled me over his arms so I didn't hurt myself. He took the hit."
