Marisa Miller and husband Griffin Guess are expecting their first child!

According to People, the former Victoria's Secret model expressed her feelings on starting a family.

“My husband and I have always looked forward to starting a family, but also wanted to enjoy just being married,” Miller said. “After six years together, the time feels right. My sisters and I will all have babies in 2012 so it’s such an exciting time.”

The 33-year-old model and actress is due in late fall.

Marisa Miller definitely said it! During her recent interview for Women's Health, supermodel Marisa Miller dished on how she keeps the spark in the bedroom alive with husband and music producer Griffin Guess.

The 33-year-old babe, who enjoys dressing up for her man, tells the mag:

"Guys are very visual. My job is great, because I come home from work every day made over. So Griffin can get 20 different women in one month."

Lucky man, indeed! As for her ridiculously hot bod, Miller says nudity helps a lot. She adds:

"So when you're trying to lose weight, spend more time wearing less. I don't think I could eat a plate of nachos naked - could you?"

Thanks for the visual, Marisa!

Marisa is one of the lucky few who doesn't dread bikini season!

The Sports Illustrated swimsuit cover girl frolicked along the beach in her teeny bikini with sexy hubby, music producer Griffin Guess, in San Diego's posh La Jolla area. The Santa Cruz native is a California girl at heart, so she loves hit up the west coast beaches.

If we had a body like that, we'd live on the beach in bikinis 24/7!

The Victoria's Secret Angel recently graced the cover of Boston Common in some haute couture ensembles. Check out the sexy BTS video from Miller's shoot, after the jump ...

Super model, and beloved Victoria's Secret Angel, Marissa Miller is in serious talks to join the Simon Cowell's U.S. X-Factor as a host.

While it's unclear just how much the Sports Illustrated swimsuit model knows about music (Ryan Seacrest was a DJ for years before he nabbed the Idol gig) it's a great way to get the guys to watch!

If Marisa does land the job she may have to share her hosting duties with former Pussycat Doll Nicole Scherzinger. It's been reported Cowell had already offered the sexy singer the job, but will she mind sharing the stage with Marissa?

Marisa Miller goes completely nude for Marc Jacobs‘ new campaign for charity, which benefits the NYU Cancer Institute at the NYU Langone Medical Center.
