Jessie J is too busy to accept roles in films.

The 'Bang Bang' hitmaker admits she would like to star in a movie, but says her packed working schedule means it's tough to find the time.

The 26-year-old singer-songwriter - who is appearing as a judge on 'The Voice' in Australia - explained: ''I've been offered a role in a massive movie with one of the biggest American actors but I don't know if I can do it.

''I would love to do it but it's at the same time as I'm filming the 'Australian Voice'.

''So unless they move the filming to Sydney I'm going to have to turn it down.''

However, Jessie revealed she's now working under new management and is determined to find time to star in a film.

She told the Daily Star Sunday newspaper: ''I was offered a part in the Paul Potts film.

''I did a script reading and took the part but in the end my schedule didn't work.

''The part of Night B***h in 'Kick Ass 2' was written especially for me.

''It would have been amazing but I couldn't do it because of other commitments.

''I've got new management now and we are trying to plan it so I don't keep missing things.''
