Before the couple booked it home, they talked with ET's Nancy O'Dell and Kevin Frazier on the carpet about potential baby names--and referred to the baby as "her" at the time.
"If we had a name, you could say it," Teigen said, admitting that she and Legend didn't figure out daughter Luna's name until the last minute.
"Luna's we figured out 3 days after she was born," the 32-year-old admitted. "When they finally said they were gonna kick us out and we had to pick a name and then we picked it," she added, joking about the hospital staff.
Teigen did drop another potential hint before the GRAMMYs. On the red carpet for the Clive Davis Pre-Grammy Gala Saturday night, Teigen told ET, "I hope baby two is like John a lot." It seems like it could have been a little tease about the baby's gender, but she was ultimately referring to their personalities, especially when she quipped, ""Baby Luna's more like me...and I realized I can be difficult."
