Noah Shannon Green is a Big Apple baby! Megan Fox's six-month-old son made a rare public appearance with dad Brian Austin Green in NYC's Soho neighborhood on Friday, March 29 -- kicking back in a stroller as his father, 39, pushed him down the sidewalk.

In a rare glimpse of the Hollywood tot, Noah showed off long eyelashes and adorable chubby cheeks as he sucked on a pacifier and snoozed, bundled up in a blanket and with a knit, sock-monkey hat. Born in late September 2012, Noah is the first child for Fox, 26, and Green, who celebrate their third wedding anniversary this June. Noah has a big half-brother in 10-year-old Kassius, Green's son with ex-girlfriend Vanessa Marcil. But if Fox has her way, there will be other little ones joining the household soon enough.

"All I wanted to do my whole, whole life was have a baby and, now, I've finally done it," the This Is 40 actress recently told Marie Claire. "I just want to give Noah as much of myself as I can. And I want to have more kids. That is where my heart is."

As for her very happy union with Green? "I believe he's my soulmate," she mused of the Beverly Hills, 90210 star. "But that doesn't mean it doesn't take work, because we are very, very different. But we are tolerant of each other and we try to be patient with each other, and I don't try to turn him into me and he knows not to try to turn me into him. He really is amazing. I should never, ever even think about complaining."
