Since announcing her pregnancy in November, she and husband John Legend, who are parents to 21-month-old daughter Luna Simone, have kept the sex of the baby on the way under wraps.

“We’re not ready to say what it is yet,” Teigen told PEOPLE on Wednesday at a junket for Lip Sync Battle LIVE: A Michael Jackson Celebration. “We did the harvesting — as they call it — again, where they make the embryos,” she said about conceiving through IVF again.

And with IVF, Teigen revealed there was no long wait before her pregnancy was confirmed — the couple knew just 11 days after treatment.

“You get the phone call and you’re like, ‘Please, please, please,’ and then you get the result and then you’re so excited,” she recalled. “It does make for a very long-feeling pregnancy because you know so early.”

Though they already know if they are expecting a boy or a girl, finding the right name for their unborn child has taken some time.

“We didn’t have Luna’s name until three days after she was born,” she said. “We love going the music route. John loves looking at who he grew up with or people he grew up listening to. And maybe we’ll have a little baby Todd Smith, I don’t know. Maybe we’ll have a little Simone.”

Adding, “It’s hard.”
