Sorry men of the world, Kate Upton is officially off the market.

The 20-year-old Sports Illustrated swimsuit model -- who recently posed nude for Cosmopolitan‘s November issue -- is dating baseball MVP Justin Verlander, multiple family members confirm to Celebuzz.

Verlander’s grandfather, Richard Verlander Sr., told Celebuzz: "I heard he has been on dates with a Sports Illustrated girl. I saw a photo -- she’s beautiful.

"They make a good looking pair because he’s a good looking man too," said his proud granddad.

"I do know he’s on the dating scene. Justin is a fine boy and whoever he ends up with is lucky. He’s not only a great baseball player, he’s a great guy," he gushed.

Rumors have swirled since July about the twosome, including numerous sightings and Twitter reactions of the dating duo getting cozy in Detroit.

The Michigan native has stayed mum on her relationship status, even playing coy about divulging who she was dating when she appeared on the Ellen Show in February.

Ellen DeGeneres quizzed Upton about her relationship status and rumors about her dating Eva Longoria's beau, Jets quarterback, Mark Sanchez.

When DeGeneres asked about what Sanchez thought about the magazine cover, she replied, “He’s cute. Even if I had a boyfriend, I wouldn't ask how he felt about it.”

Upton’s grandfather also seems pleased about her latest love interest. Stephen Upton told Celebuzz, “She has all of our support.”

The blonde beauty recently cheered her 29-year-old boyfriend, who's a pitcher for the Detroit Tigers, from the stands.

“She was at his first game in Detroit against Oakland,” he said of the Oct. 6 game.

One thing’s for sure, the supermodel knows what she likes in a man. “I find a sense of humor sexy in a man. Someone who is just relaxed and can have a good time," she said in that Cosmopolitan in issue.
