The "Ballers" and "Furious 7" star is already dad to 14-year-old Simone Alexandra Johnson with ex-wife Dany Garcia, his manager and producing partner. He and Garcia, who met during college at the University of Miami, were married from 1997 to 2007, finalizing the split with a divorce agreement in 2008.

Johnson reportedly met Hashian, 31, a singer-songwriter, while filming the 2007 sports comedy "The Game Plan," and they are parents to a French bulldog puppy named Hobbs. (Hobbs' brother, Brutus, known for making Papa Rock jump into a pool after him, died in September after eating a toxic mushroom).Rumors that Johnson and Hashian were expecting popped up in September with Johnson only confirming the reports on Tuesday.

In a June interview, Johnson spoke up about the women in his life, telling Esquire that his girlfriend and daughter are often overlooked.

"We do these stories and we talk so much about the business end, the success end, but then Lauren isn't mentioned and my daughter [Simone] isn't mentioned," he told the mag. "I always like making sure we find the balance and my home life is in there and Lauren Hashian is in there and my daughter is in there. You gotta get the better half in there. With all the ... success that I've been lucky enough to get? That doesn't happen unless the home life is solid."

No word yet on the child's expected due date. As for baby names that can only be hewn from the Rock? We're rooting for Pebbles.
