Chrissy Teigen and John Legend's band is growing once again.

Five months after the Cravings author gave birth to daughter Esti, she and the "All of Me" singer have welcomed a baby boy via surrogate, a son named Wren Alexander Stephens.

In addition to Esti, the bundle of joy—born June 19—joins the couple's kids Luna, 7, and Miles, 5, in the Stephens squad.
