Molly Sims and her husband are expecting their first baby.

The model and actress, who has graced the pages of many a Sports Illustrated Swimsuit Issue, made the announcement on her fashion and beauty Web site.

Our little bundle of joy is a honeymoon baby, due at the end of June, she wrote. A first pregnancy is a nerve-wracking experience of course, but mostly we are just thrilled and excited. We can't wait to meet him or her.

She also informed fans via Twitter: Big news... I'm having a baby!

Sims is married to producer Scott Stuber, whose work includes Love and Other Drugs and the television series Whitney.

Stuber was previously married to actress Rachel Nichols. He and Nichols split up in 2009 after seven months of marriage, according to a People magazine report.

Sims wrote about breaking the news to Stuber via fortune cookie: I hijacked the fortune cookie and typed a new message so that when he opened his cookie at the end of the meal, he found out he was going to be a daddy. You can only imagine how nervous I was during the entire meal (I think I ate a total of two bites...), but the look of surprise and pure joy on his face was priceless.
