"I feel really good, and I have a tonne of energy,” Teigen tells WHO about her second time around. “I don’t know if it’s the IVF, but I feel like I’m so prepped for pregnancy that by the time we're actually pregnant, just having it happen is a relief."
And there could be more babies on the couple's horizon. The LipSync Battle cohost says going through the fertility process this time also gifted her with "viable, perfect embryos" for the near future.
"I just wanted to gather as many as possible. I don't want to have to do this again for the rest of my life," she says. "I thought it'd be nice to get a great batch of beautiful embryos [in case we want to] keep trying.
As far as soon-to-be big sister Luna goes, Teigen admits her 22-month-old girl is way less interested in having a brother than she is in perfecting her talking skills. "She's a parrot right now, basically," Teigen says. "She says things that she really things mean something, and we're trying to decipher what it is. She really lights up when she knows she made people laugh!"
