Megan Fox fell "instantly in love" with her husband Brian Austin Green.

The actress didn't recognise the former Beverly Hills 90210 star when they met on the set of US TV series Hope and Faith in 2004, but was immediately attracted to him.

Despite a 12-year age gap the couple got engaged in 2006 after dating for two years. They briefly split in 2009 but made up later that year and got married in Hawaii in the summer of 2010.

"I was too young to remember Beverly Hills [90201], so I didn't know who he was. But I was instantly in love," Megan told US publication Miami.

The Transformers star also revealed that she is a closet nerd and would love to go to an archaeological site.

The brunette beauty also named the super hero powers she would most like to possess.

"Surely you know one of my favourite shows is Ancient Aliens!" she said. "[My favourite super power would be] invisibility. It's how you gain the most advantage, at least in practical situations. I would also need super strength, but that's a given."
