Just call her Kim the Kougar!

In a flirty new photo shoot for Elle magazine's September issue, 29-year-old Kim Kardashian frolics with 16-year-old pop idol Justin Bieber on Paradise Island in the Bahamas.

The portfolio, shot by Kevin Keiser, shows Kardashian channeling Italian film actresses of the '50s and '60s with wavy jet-black hair and pouty red lips, while the Proactiv pitchman plays her adoring fan (and nothing more, we hope -- he's 16!).

In one shot, Kardashian models a black-and-white striped Dior coat; black Agent Provocateur camisole, Wacoal bra, and Undrest tap pants; Charles Anastase by Linda Farrow Projects sunglasses; and giant gold hoop Laruicci earrings as Bieber -- in a Marc Jacobs T-shirt and A.P.C. jeans -- snaps her photo.

Another shot shows the pair splashing around in the surf -- Kardashian clad in a soaking-wet, slinky Vera Wang dress and Bieber in a Marc Jacobs shirt and Dior Homme pants.

But this isn't the first time the pair has made waves. Beliebers everywhere were P.O.'ed at Kardashian in May, after the singing sensation tweeted a photo of them together at the White House correspondents' dinner with a caption that read, "Look it's my girlfriend."

"I started to get death threats from 10-year-old girls, saying that I stole their man and they were gonna come find me," says Kardashian, who also models a cotton crochet Burberry dress inside the magazine. "So I Twittered Justin and let him know that his Beliebers want to kill me."

Before anyone could kick Kardashian's famous derriere, Bieber calmed the masses, tweeting to his tween followers, "ladies calm down. @kimkardashian is a friend. a very sexy friend but a friend. no need 4 threats. Let's all be friends and hang out often ;)."

Kardashian was relieved, but as she tells Elle in an exclusive behind-the scenes video, "I don't get how people would think that that's, like, serious. Sorry Biebs!"

Day-um!
