The model has worked for Victoria’s Secret and covered Sports Illustrated during her career and is now moving on to a new phase of her life.
The 33-year-old star has confirmed she and her husband Griffin Guess are to become parents later this year.
“My husband and I have always looked forward to starting a family, but also wanted to enjoy just being married,” she told People.
“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.”
Marisa and Griffin’s bundle of joy is due in late fall and they couldn’t be happier.
The pregnancy has already started to change the stunning model’s body but she is relishing every moment of being with child.
“Even though I’m exhausted, gaining weight and breaking out from all the hormones, I’m really enjoying my pregnancy. It’s all for the baby so I couldn’t care less!” she gushed.
