Rumer Willis to swap acting for singing?

Rumer Willis's Sorority Row co-stars have tried to convince the star to pursue a singing career.

According to Contactmusic, Willis impressed the cast at impromptu after-hours singing sessions.

Jamie Chung said: "We had a grand piano in our hotel and we'd come in and she was just jamming and singing. She has the most incredible voice."

The 21-year-old daughter of Demi Moore and Bruce Willis has launched an acting career in recent years, also appearing in teen TV show 90210.

Sorority Row is due in cinemas on September 9.
