The 34-year-old actor gushed over his wife, Hannah Bagshawe, and their future addition to the family on the Screen Actors Guild Awards red carpet on Saturday afternoon.

“Hopefully it's all going according to plan. Hannah seems really well," Redmayne told ET's Nancy O'Dell of Bagshawe's pregnancy.

But there is one thing the couple will keep a surprise: the gender!

"We don't know the sex of the baby," the SAG Award nominee revealed.

Even so, the couple -- who married in late 2014 after dating since 2012 -- have already started dreaming up baby names.

"In the middle of the night last night -- we arrived from London -- at 4 in the morning we started mumbling names to each other," Redmayne recalled. "We're two of the most indecisive people in the world!"

News that Redmayne and Bagshawe were expecting their first child surfaced on Christmas Eve.

Last January, Redmayne playfully teased his wife for being late to their wedding.

"[My wife] has never been on time for anything in her life," he told Ellen at the time. "She was a good half-hour late. Her grandfather had to be some help from going and summoning her."
