Chrissy Teigen's Baby No. 4 Comes Five Months After Their Baby No. 3

Wren Alexander Stevens, John Legends, and Chrissy Teigen's baby no. 4 came five months after Teigen, 37, and Legend, 44, welcomed their third baby, a daughter named Esti.

The couple already has two other children, Luna, aged seven, and Miles, aged four, the Daily Mail noted.

Chrissy openly shared her experience of undergoing IVF again and becoming pregnant with Esti, despite initially not intending to carry another child herself. It is interesting to note that she and Alexandra were pregnant at the same time. Chrissy discovered her pregnancy with Esti first, and Alexandra became pregnant with Wren shortly after.

Chrissy fondly recalls her childhood desire to have four children, with two glow worms and two cabbage patch dolls always by her side, engaging in imaginary play in her pretend kitchen while watching the show "Alf." They would sleep together every night, receiving equal kisses to ensure fairness.

Her mother would actively search for a Pound Puppy with four pups in its pouch, unhesitatingly opening and peeking inside the packaging before making a purchase.

"Thank you for choosing me. For making this whole experience so wonderful," she wrote. "For loving me and my family wholeheartedly. It was truly an honor bringing perfect Wren into the world with you right by my side️."

Teigen also acknowledged the presence of their late son, Jack, whom they tragically lost at 20 weeks in September 2021.

"We know both their angel kisses are from you," she said.
