Eddie Murphy is expecting his 10th child with his Australian girlfriend

Eddie Murphy is about to be a dad again.

The 57-year-old already has nine kids with five different mothers -- and he and his 39-year-old Australian girlfriend are adding to the family.

"Eddie Murphy and longtime girlfriend Paige Butcher are pleased to announce that they are expecting their second child in December," a rep for Murphy said in a statement this week.

The couple, who have been dating since 2012, are already parents to Izzy Oona, 2.

Meanwhile, the Beverly Hills Cop star has eight other kids from previous relationships.

His eldest is Eric, 29, whom he shares with Paulette McNeely.

Bria, 28, Miles, 25, Shayne Audra, 23, Zola Ivy, 18, and Bella Zahra, 16, are the children he welcomed while married to model Nicole Mitchell Murphy.

Murphy also has a 27-year-old son, Christian, with Tamara Hood and an 11-year-old daughter, Angel Iris, with Mel B.

Butcher and Murphy met on the set of Big Momma's House 2, in which the Perth-born model had a minor role. She has also appeared in the 2003 film Something's Gotta Give.

When Butcher and Murphy began dating, she deleted her entire social media presence.

"I'm in a relationship with a celebrity, so I felt like there’s already enough of me out there," she told Vanity Fair in 2013. "I felt like I was giving out too much information. I was giving people too much access. I like to keep as much private as possible now."

Prior to dating Murphy, Butcher was reportedly in relationships with musician Russell Simmons and model Tyson Beckford.
