Just hours before welcoming their newborn into the world, Chrissy revealed she had been enjoying bath time with Luna.
Chrissy Teigen has definitely taken one name off the list for her son!
And while we are overjoyed by Chrissy and her husband John Legend's exciting news, things weren't smooth sailing when it came to conceiving both their kids.
Their son joins 2-year-old daughter, Luna Simone Stephens, making them now a family of four.
Although the post didn't specify a gender, Teigen announced some time ago that she was expecting a boy. Chrissy Teigen 32, officially gave birth to her second baby with John Legend, 39.
Earlier this year, "Extra's" AJ Calloway caught up with Chrissy, who revealed, "I personally love being pregnant, so I got lucky there". I'm really lucky because some men start to look at you like a tool, I've heard, so I've been scared and don't let that happen to me! Chrissy knew at 11 days! But now that he is here is Luna going to want to return her big brother? "That's why I stand for a real core group of people around me", she said. "A boy. So. Yeah", she wrote on Twitter, referring to the couple's highly publicized use of in vitro fertilization.
