Megan Fox is an "amazing" stepmother.

The 25-year-old actress has forged a strong bond with nine-year-old Kassius, her husband Brian Austin Green's child from a previous relationship, and the actor loves seeing them together.

Brian said: "She's an amazing stepmom. My son loves her. They have a great relationship. She's always had a special bond with him. They love each other to death.

"She's been in my son's life since he was two. She's been amazing."

Megan says she has always related well to children and can't wait to have kids of her own.

She told People: "I've always really loved kids. I was a good babysitter. I've always loved babies. I relate to kids pretty well.

"Of course [I want kids]. It will happen when it's meant to happen."

Megan recently revealed she was nervous the first time she met Brian but she was unaware he was in 'Beverly Hills, 90210' as she was "too young" to watch it.

She said: "I didn't know who he was. I was too young for 'Beverly Hills, 90210'.

"But the first time I saw him, I got butterflies. And the first time he casually touched me? There was so much electricity."

Megan and Brian first met on the set of 'Hope and Faith' in 2004 and got engaged in 2006 before briefly splitting in 2009, only to get back together and tie the knot in 2010.
