Congratulations to Jessica Simpson! The proud mama of daughter Maxwell Drew, born May 1 of this year, is expecting her second bundle of joy!

Us Weekly reports that Simpson, 32, and fiance Eric Johnson, 33, were pleasantly surprised by the news. "It definitely wasn't planned. But yes, Jessica is pregnant again," a source said. She really is overjoyed!"

Simpson couldn't have been happier with baby Maxwell, so we can only imagine how thrilled she is right now. Life has completely changed," Simpson said back of her little girl. "From how I sleep to what I think about, Maxwell has definitely taken over everything!” She even loves breast feeding Max, revealing, “It’s the worst if I have to pump and give Eric a bottle to give her. I miss holding her and having that closeness.”

Now Simpson will have double the fun -- and double the work. We bet she's glad to be launching her maternity line soon, because it'll come in handy for her now! Though we do wonder how this will effect her deal with Weight Watchers.

Considering how cute Maxwell is, we can't wait to see pics of Jess and Eric's new baby. Our best wishes to the happy family!
