NEW YORK (AP) – John Legend and Chrissy Teigen (TEE’-gen) have welcomed a baby girl named Luna Simone Stephens.

Legend’s real surname is Stephens. He and Teigen announced the birth of their first child on social media Sunday. Their daughter was born Thursday.

The 37-year-old R&B star and the 30-year-old model married in 2013.

They announced the pregnancy in October after Teigen opened up about their fertility struggle and how she had undergone in vitro fertilization treatments.
