"I'm writing a movie right now. It's very action packed," the bikini-clad reality star, 23, told UsMagazine.com Sunday at the opening of the Liquid Pool Lounge at Las Vegas' Aria Resort & Casino.

"It's Bourne-meets-Barbie," adds Montag, referring to Matt Damon's action flicks. Montag would would "of course" play the starring role.

"I would love to be an action star," continues Montag, who recently Twittered she wants to to be the "blonde 'Tomb Raider.'"

"I've trained in knife fighting and guns for over two years with one of the founding members of Saw, [who] was [in] the original Delta Force. So I've been shooting and practicing the whole real-life action figure for years," she said. "So I'm very excited to have action roles."

Montag recently filmed a cameo in "Just Go With It" alongside Jennifer Aniston. Whose acting career would she rather emulate: Aniston's or the more action-packed Angelina Jolie's?

"Actually, I want a combination of both," says Montag, who was flanked by six bodyguards at the event.

In the meantime, don't expect her to appear on "Dancing With The Stars" any time soon. When asked if she'd compete, she told Us, "I would love to host."
