Lady GaGa wants to make a movie.

The 'Poker Face' singer - who recently made her acting debut in an episode of US drama 'Gossip Girl' - is reportedly determined to pursue her dramatic ambitions further and has set her sights on a big-screen musical adventure.

A source said: "She sees acting as a natural progression in her career. "One idea she has is for a rock opera which would be a huge, big budget movie made to her own very unique ideas. But she is also keen on straight dramatic roles.

"She has the drive and confidence to make it big as an actress. It's just a matter of finding time when she is not committed to her first love - music."

The 23-year-old singer recently admitted she barely has time for a social life because she has such a heavy workload.

She said: "To be honest, I'm quite insulated, and I work very hard. I don't really socialise much."
