OMG! Channing Tatum posted a dripping wet, nearly naked image of himself to Instagram, with almost every inch of his rock-hard pecs, biceps, abs, legs okay, you get the drift on full display. The only thing preventing a Full Tatum? His two strategically placed hands. As it turns out, girlfriend Jessica Cornish (aka singer Jessie J) was to blame (or, rather, profusely thank) for the image.
