Chrissy Teigen and John Legend are now the proud parents of a baby girl.
The swimsuit model and Grammy award winning crooner welcomed little Luna on Thursday.
"She's here! Luna Simone Stephens, we are so in love with you! And sleepy. Very sleepy," Teigen wrote along with a snapshot of a readout of Luna's weight, 6 pounds 11 ounces.
Legend, who was born John Stephens, also took to social media this weekend to celebrate becoming a parent.
"Our new love is here!" the singer wrote. "We couldn't be happier!"
Kris Jenner, whose daughter Kim Kardashian is friends with Teigen and reportedly threw her baby shower, was among the first celebrities to congratulate the couple on the new addition.

Teigen, an active social media user who shared many of the ups and downs of her pregnancy, caused a stir when she revealed to the world that she'd chosen the sex of her embryo following in vitro fertilization.
“I’ve made this decision,” Teigen told People in February. “Not only am I having a girl, but I picked the girl from her little embryo. I picked her and was like, ‘Let’s put in the girl.’”
Teigen has also indicated that Luna will be the first of many.
“The number of embryos we have left is not matching the number of people I want at my dinner table, so I’ll have to do it again,” Teigen said.
