Marisa Miller Expecting Second Child

Marisa Miller is pregnant!

The model and actress her husband, record producer Griffin Guess, are expecting their second child in late spring, the couple tell PEOPLE exclusively.

“Being a mother has been the biggest blessing in my life. To get to experience it all over again is really exciting,” says the former Victoria’s Secret model and Sports Illustrated cover girl.

The baby will join the couple’s 22-month-old son Gavin Lee.

The mom-to-be, who bared her bump in a series of nude photos while expecting her first child, is all about embracing her body.

“I always felt, even before I got pregnant, that it’s better to accentuate your curves,” Miller said. “Obviously you can’t suck it in, but it’s important to really show off the belly.”

Miller, who costarred with Ryan Reynolds in R.I.P.D. in 2013 and will appear in an upcoming PETA campaign, and Guess were married on April 15, 2006.
