In her new movie, Friends With Kids, Megan Fox plays a woman who has no interest in children – something that couldn’t be further from the truth for the actress in real life.

“I’ve always really loved kids,” Fox, 25, told PEOPLE at a PEOPLE StyleWatch and Cinema Society-sponsored screening in New York City Monday. “I was a good babysitter. I’ve always loved babies. I relate to kids pretty well.”

She might be referring to one kid in particular: her husband Brian Austin Green’s son, Kassius Lijah Green, who turns 10 next week.

“She’s an amazing stepmom,” Green told PEOPLE at the event. “[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 2,” he added. “She’s been amazing.”

In fact, Green said, the trio recently returned from a trip to Hawaii, where he and Fox were married in 2010. Their family vacation activities included scuba diving and snorkeling, according to Green.

As far as Fox having her own children someday, the actress responded: “Of course. It will happen when it’s meant to happen.”
