Brody Jenner: Mellowed by Jayde

If most guys suddenly found themselves dating 2008’s Playboy Playmate of the Year, they’d conclude that their life is going just fine and it would be foolish to change course.

Not Brody Jenner.

The Bromance star, who began dating 22-year-old Playmate Jayde Nicole last fall, tells People magazine that his lady-love has caused him to make drastic changes in his lifestyle—and he likes it.

Jenner admits that he’s a lot less likely to hit the clubs now, and that the two prefer quiet evenings at home than hitting up the hotspots.

“We stay in, maybe bake cookies,” Jenner says. “It sounds kind of lame, I know—sorry, boys!—but we bake some cookies, watch DVDs and have nice quality home time.”

Cozying up to the hard-bodied beauty has also inspired the Bro-meister to take his own health more seriously, he continues.

“[For the New Year], I completely quit drinking and I’ve been working out every day and eating the healthiest I’ve ever eaten my entire life,” Jenner reveals, adding that Nicole is “in amazing, amazing shape” and feels “incredible.”
