"I am absolutely, positively, downright over the moon to announce that we are pregnant! There are simply no words to describe the feeling," Sims announced on her blog. "I finally get what they mean when they say pregnant women GLOW. Our little bundle of joy is a honeymoon baby, due at the end of June. 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."

The couple wed in Napa Valley, Calif., in September after dating for just over 18 months. A friend tells Life & Style magazine, "She's very happy. She's wanted to be a mom for a long time."

Just last month, Sims told the publication, "(I want to have) as many children as I can have."
