London, Nov 14 While Robert Pattinson has not said no to a professional singing career, he claims to be too scared to release his songs.

The 'Twilight' hunk has hinted many times how much he loves music, and has even showcased his stunning vocals on the movie's soundtrack.

In fact, Pattinson performed a secret impromptu mini gig in London earlier this year (09).

However, the British actor is worried about releasing solo music professionally - unless his film roles dry up.

"I do do a bit (of singing) but I don't really release it. I'm too scared. Maybe one day. I think you can only concentrate on one or the other. Once I'm ready to do it, I'll do it again, I'll perform again," The Daily Star quoted Pattinson as saying. (ANI)
