It was time to get musical as Keira Knightley and Mark Ruffalo were spotted filming scenes for "Can A Song Save Your Life" in New York City on Friday (July 20).

The dazzling duo had a blast while they showed off their musical talents during a performance scene shot in Central Park.

As previously reported by GossipCenter, the "Avengers" star and the brunette beauty were recently spotted with Hailee Steinfeld enjoying frozen treats while they cuddled up during an outdoor scene for the flick, which is set to release in 2013.

In the John Carney directed flick, a dejected music business executive forms a bond with a young singer-songwriter who is new to Manhattan. It also stars Maroon 5 front-man Adam Levine.
