*The Rock has a new pebble in the family.

Dwayne Johnson and longtime girlfriend Lauren Hashian welcomed a baby girl on Wednesday.

“Both Mom and Dad are over the moon; Christmas definitely came early,” a source told People.

This is Johnson and Hashian’s first child together. The actor is already a dad to 14-year-old Simone with ex-wife Dany Garcia.

Earlier this week, the new mom took to Instagram to express just how excited she was about motherhood.

“So grateful and in awe of this time. To experience creating a little life is just incredible. This beautiful cycle of life and womanhood beginning again. And like Big Daddy says – Couldn’t be prouder of all the kickass woman she’s going to have around her! And Men of course ;).”
