Sarah Jessica Parker performed a duet with her nine-year-old son James as a 50th birthday present to husband Matthew Broderick.
The 'Sex And The City' star - who has son James Wilkie, nine, and twin daughters Tabitha and Marion, two, with the actor - organised a surprise party on Sunday (18.03.12) at New York's River Cafe venue.
However, the highlight of the evening was when the actress and son James took to the stage to perform a rendition of The Beatles classic 'Here Comes The Sun' as a gift for Matthew.
An insider told the New York Post newspaper: ''He's a little Broadway star in the making!''
However, despite James' performing skills, Matthew recently admitted his twin daughters were ''more self-sufficient'' because they cannot always both get attention at the same time.
He said: ''It's kind of sad with twins; they learn to, like, lie on the pillow because you can't always hold them both. They're more self-sufficient. They learn to take care of themselves.
''They are really very attached to each other. They're really cute.''
