It’s Official: Justin Theroux’s Jen-Whipped!

Proving he’s TOTALLY new wife Jennifer Aniston’s bitch, Justin Theroux — in Texas filming his HBO drama “The Leftovers” – waved an arm while rehearsing a scene with co-star Regina King and knocked an open water bottle smack into her lap!

Said My SpyWitness: “Instantly, Justin jumped up and started patting Regina’s dripping wet crotch with paper towels — but she instantly yelled, ‘Don’t you even TOUCH me! … Your WIFE will have a fit!’ Turning beet-red as cast and crew exploded in giggles, our P-whipped newlywed groaned, ‘Damn, you’re right — if Jen saw a photo of my hands on you, my life would be OVER!’”

Cracked a crew member: “Looks like she’s got you pretty damn trained ALREADY, Justin!”
