Gretchen Mol Has a Baby Boy

3:10 to Yuma star Gretchen Mol gave birth to a boy

named Ptolemy John on Sept. 10, her rep announced. He is the first

child for the 34-year-old and her husband, director Tod "Kip" Williams, 38.

When OK! caught up with Gretchen at the July The Ten premiere, the actress told us she was looking forward to meeting her son so she could finally name him.

“I have a feeling I'm going to end up with a shortlist, and then finally see who he is, and hopefully he'll say, ‘I'm so-and-so.’ I don't feel right about deciding before.”
