Marisa Miller has a bun in the oven!

The supermodel, 33, and her husband, record producer Griffin Guess, 32, are expecting their first child, her rep confirms to Us Weekly. Miller is due late fall.

Miller and Guess tied the knot on April 15, 2006. Though she was ranked No. 1 on Maxim's Hot 100 list in 2008, the California girl only has eyes for her husband.

"My job can definitely bring out a lot of insecurities or trust issues, but I'm so thankful we never had that. I don't give my husband a reason to worry," she once told Vegas magazine. "Those kind of things can become a big problem in any relationship, and then especially with [my life] there's a whole new set of challenges."

Miller, a former Victoria's Secret angel and Sports Illustrated cover girl, next appears in the movie R.I.P.D. with Ryan Reynolds, 35, and Jeff Bridges, 62.
