Chrissy Teigen and John Legend announced Wednesday on social media they have welcomed a baby boy via surrogate.

The child is the couple’s fourth.

“We want to say thank you for this incredible gift you have given us, Alexandra,” Teigen said of the surrogate, via Instagram. “And we are so happy to tell the world he is here, with a name forever connected to you, Wren Alexander Stephens.”

The baby boy was born on Monday, June 19.

“Our hearts, and our home, are officially full. And to our Jack, we know both their angel kisses are from you.”

The couple’s new arrival comes just five months after the family welcomed baby Esti.
