Brian Austin Green & Megan Fox: Dinner With Kassius

Beverly Hills, 90210 alum Brian Austin Green and wife Megan Fox took his handsome 9-year-old son Kassius out to dinner at BOA Steakhouse in Santa Monica, Calif. on Sunday night (September 4). Megan looked stunning in a red maxi dress alongside the smiley Green boys.

Kassius is about to become a big brother! His mom, Green's ex-girlfriend General Hospital star Vanessa Marcil-Giovinazzo, and her hubby Carmine Giovinazzo are expecting their first child together.

Brian has said Megan is an amazing stepmom to his only child.

"She is absolutely my better half in parenting," Brain said. "She just gets it. It's instinctual for her. She loves my son, Kassius. And from the time we started dating - you know, she was 18 - she stepped in and took control. It's unbelievable. At 18, I was like, 'Hey, which club is open tonight? And how cool do my pants look? Can I sneak a drink across the bar without getting caught?'"
