Kathy Griffin to Kim Kardashian: Justin Bieber’s Mine!

Watch out, Kim Kardashian!

Days after the reality star was spotted holding hands and frolicking in the ocean with Justin Bieber at The Bahamas' Atlantis resort, comedian Kathy Griffin is warning Kardashian to stay away from her man.

"I'm taking that bitch down," Griffin joked to UsMagazine.com during a visit to our New York City office Monday.

What is it about 16-year-old Bieber that makes Griffin swoon?

"I like his hair, his music…I'm a 'belieber,'" the My Life on the D-List star enthuses. (Watch the video above)

Griffin already has a plan in place to woo the teen superstar.

"I will make some sort of inappropriate tape with Justin Bieber. I'm not saying it's a sex tape, because I don't know how old he is — I think he's about 30 — but I hope that I'm his 'somebody to love,' Griffin says, taking a cue from the title of Bieber's single. "So screw you, Kim, he's mine!"

For more on the comic's love for Bieber — and her take on other hot Hollywood topics — check out the video above.

The sixth season of Griffin's My Life on the D-List premieres June 15 at 9 p.m./ET on Bravo.
