Josh Duhamel plans to be in the delivery room when his wife Fergie gives birth to their first child, but she has some strict rules! The Safe Haven actor, 40, told Chelsea Handler on Chelsea Lately Wednesday, April 3 that he's only allowed to witness the birth from the waist up.

"I will be there. She says that I can't be anywhere below right here," he explained, pointing to his chest. "You know, because some women get nervous about the actual birthing process."

"Some men don't recover from that in all fairness," Handler joked.

"But for me," he added. "I think it's a beautiful thing."

Duhamel also revealed that this baby-to-be was a long time in the making for the couple of four years. "We've been trying for the last year or so," he shared. "We've been trying for this for quite a while."

Fergie, 38, recently admitted to Good Morning America that she has "no idea" what she's doing as a first-time mom-to-be. She said, "I'm just going to play it by ear and see how things go, and let the natural instincts kick in."
