The seven-time Tour de France winner has three previous children with ex-wife Kristin Richards.

As previously reported on Access, Lance and ex-girlfriend Sheryl Crow's split over the rocker's desire to have kids.

"She wanted marriage, she wanted children; and not that I didn't want that, but I didn't want that at that time because I had just gotten out of a marriage, I'd just had kids [Luke, Grace and Bella]," Lance says in his July-due biography, "Lance." "Yet we're up against her biological clock — that pressure is what cracked it."
