Listen to Christina Aguilera Radio on iHeartRadio

Christina Aguilera has named her daughter Summer Rain Rutler.

The singer and Matthew Rutler welcomed their first child together on Saturday.

“So proud to welcome our beautiful daughter Summer Rain Rutler into the world,” she tweeted early on Monday.

The baby joins older brother Max, 6, from Aguilera’s first marriage to Jordan Bratman.

Earlier this month, "The Voice" coach showed off her pregnancy curves in a stunning naked spread for V magazine.

But, as Gossip Cop exclusively reported, claims she will be posing for Playboy next are entirely false.

Congrats to the growing family!
