Calvin Klein's Model Boyfriend Is A Stunner—And He Has A Twin!

The designer and muse Kevin Baker have been spotted together on the red carpet and vacation.

Has Cupid hit Calvin Klein again? The designer, 74, has been spotted frequently with model Kevin Baker. While the couple hasn't addressed their relationship publicly, they have appeared on the American Ballet Theatre red carpet together holding hands.

Baker also posted a recent video from St. Barth's, where Klein was just spotted by paparazzi with a "mysterious" shirtless younger man.

More recently the two were spotted getting off a helicopter in the Hamptons in August.

Baker, 29 hails from Spokane, Washington.

Klein was married to Jane Centre from 1964 to 1974, and the two are parents to TV producer Marci Klein. He later wed assistant Kelly Rector in 1986, and the two remained married—at least in name—until 2006.

After coming out as bi, he dated 21-year-old porn actor and model Nick Gruber, beginning in 2011. Gruber proved to be something of a wild child, though, getting arrested on cocaine charges and being thrown out of Fire Island's Ascension party.

Baker seems a lot more level-headed, though x-rated videos he appeared in did resurface.

In potentially unrelated news, Baker is a twin: His brother, Joel, is also a model.
