Congratulations are in order for Chrissy Teigen and John Legend as the couple welcomes their second child, a boy, PEOPLE confirms.

The model announced her special delivery on Twitter early Thursday.

“Somebody’s herrrrrrre!” Teigen wrote.

Legend and Teigen recently starred in a commercial for Google’s video chat app, Google Duo, in which Legend serenades a pregnant Teigen’s stomach.

No information on a name has been released yet, but the baby joins big sister Luna, who just turned 2 in April.
