"Lauren in great shape. Thanks for all of your kind messages," Cowell, 54, shared on Twitter.

This is the first child for the X Factor judge and Silverman's second. She and ex-husband Andrew Silverman have a 7-year-old son, Adam.

When Silverman, 36, became pregnant with Cowell's child, she was still married to her husband, a friend of the reality mogul. Silverman officially divorced her husband in August.
