It'll be another boy for Brian Austin Green!

Nearly two weeks after it was revealed that the actor, 48, and girlfriend Sharna Burgess, 36, are expecting their first baby together, Green announced on Instagram that the couple will welcome a baby boy "on or around the 4th of July."

"We want to thank everyone for the amazingly kind well wishes ❤️ we are really excited to be welcoming a baby boy on or around the 4th of July :))" Green writes alongside a photo of him holding Burgess' baby bump. "@sharnaburgess, I cannot wait to see you hold your/our baby ❤️😊😊"

The Beverly Hills, 90210 star is already dad to Journey River, 5, Bodhi Ransom, 7, and Noah Shannon, 9, with ex Megan Fox as well as 19-year-old Kassius from a previous relationship.

Burgess also shared the exciting news on her Instagram page, featuring a picture of Green and his kids, minus Kassius, touching her baby bump.

The couple started dating five months after Green confirmed his split from Fox after nearly 10 years of marriage in May 2020.

The exciting pregnancy news came one month after Fox announced her engagement to Machine Gun Kelly, whom she's been dating for nearly two years.

"Megan is happy that Brian has moved on," a source close to Fox told PEOPLE. "She knows that he will be great with his new baby. He is a wonderful dad to their boys."
