Which Movie Star Rolls to the Red Carpet in a Tank?

Actor cruises in over-the-top style to his A-list movie premiere

That's one way to make an entrance!

This beefed-up actor arrived to the premiere of his latest action flick and caused a total photog frenzy.

But it wasn't because he brought along his famous girlfriend—he rolled up to the red carpet in a tank with one of his costars!

Think you know who's turning heads on the turret? Find out after the jump...

It's Bradley Cooper, with Sharlto Copley, at Thursday's A-Team premiere.

And while we're pretty impressed by the big gun the guys are on, Bradley's guns aren't too shabby either.

"It was awful," B. Coop tells E! News of his hardcore training regimen to get ripped. He also said he actually wanted to quit his diet and workout routine once the shirtless scenes were over.

We love our Bradley super buff, but we'll take him as his normal Hangover self, too. Wonder what Renée Zellwegger prefers?
