Megan Fox: 'I'm a full-time stepmum'

Megan Fox has insisted that she is a full-time stepmother to boyfriend Brian Austin Green's young son.

The actress, who has been dating Green on and off since 2004, has claimed that she will never avoid her responsibility to the 8-year-old boy.

The 23-year-old told Harper's Bazaar: "I am a stepmother to the fullest extent. I have looked after Kassius since he was three 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."

Last month, Fox confessed that she has always wanted to be a mother.
