Jeremy Renner's latest mission is fatherhood.

The Mission: Impossible  Ghost Protocol star is a dad for the first time as his ex-girlfriend welcomed their baby girl on March 28, according to Us Weekly.

The baby's mom is Sonni Pacheco, a 22-year-old model whom Jeremy met on the Mission: Impossible set.

The little one's name is rumored to be Ava.

The couple is no longer together and reportedly learned about the baby after they had parted ways. 

"They used to date but it wasn't serious," says a source. 

Apparently, Jeremy was initially "being ultra-secretive about [the pregnancy], but [Sonni] has been going on about her life and not hiding it." 

However, Jeremy's pals are quite happy for him.

"Jeremy will make a great dad!" says a friend of his.

Jeremy has had a busy year, as he starred in such films as The AvengersThe Bourne Legacy, and Hansel and Gretel: Witch Hunters. He previously had earned Oscar nominations for The Town and The Hurt Locker

Congrats to Jeremy and Sonni! A baby is quite a legacy.
