Megan Fox is currently pregnant with her second child with husband Brian Austin Green, and though they just welcomed their first child together, son Noah, in September 2012, Megan has been a parent for much longer than that. Brian's first son, Kassius, whose mom is ex-girlfriend Vanessa Marcil, was a toddler when he and Megan first started dating back in 2004. "I am a stepmother to the fullest extent," the "Transformers" star told Harper's Bazaar in 2010. "I have looked after Kassius since he was 3 and he has no memory of life without me. For some reason no one wants to look at me that way, but I am responsible [for him] and I've never struggled with that, from bedtime stories to the school run."
