Actress Jennifer Connelly believes she began to develop feelings for her husband Paul Bettany after she heard him play the guitar.

The 44-year-old met her spouse almost 15 years ago when they starred alongside one another in `A Beautiful Mind`. Although there was an instant chemistry, Connelly believes it wasn't until she saw the actor's musical talent that she was really won over by him, reports people.com.

`I remember meeting him at the first read through. I thought, 'Hmm, he's really good, that guy.' He started playing guitar and it was all over,` Connelly said on "Entertainment Tonight".

The feeling was mutual for Bettany as he was in awe of her beauty when he first laid eyes on her on set of the movie.

He explained: "I've never been this close to someone that beautiful before. I remember thinking, 'I bet every man you ever met has tried to flirt with you.'"

The couple, who have children Stellan, 12, and Agnes, four, together, struck up a relationship once filming had wrapped up in 2001 and they married shortly afterwards in 2003.
