Katherine Jenkins wants to appear on 'Glee'.

The Welsh songbird made her acting debut in 2010 on cult sci-fi show 'Doctor Who's Christmas special, and says the experience opened up the possibility of future acting work on musical movies or TV programmes.

Speaking at the announcement of her new three-album deal with Decca Records held at London's Ritz hotel, Katherine exclusively told BANG Showbiz: '' 'Doctor Who' took me out of my comfort zone massively, but I did really enjoy it. I still think it needs to be something that combines acting and music. That's what was lovely about that role, she was a singing character.

''If it was a musical film... Maybe something like 'Glee'! I feel at the moment I have so many singing things and I don't get them all. It would have to be something I really cared about to take me away from that because singing would always come first.''

The 33-year-old mezzo-soprano insists she isn't intimidated by scantily-clad pop acts like Miley Cyrus and Rihanna and has no plans to change her ''glamorous'' classical music singer image.

Quizzed whether she felt any pressure to sex up her image, Katherine said: ''What I do is so different. It's a niche thing. I appreciate pop music, I've never felt any pressure to do that.

''I certainly have always appreciated the glamour side of music. Classical music can sometimes be glamorous. I've always been a girly girl, so the record company has never had to make that up, that was always [part of my image].''

Katherine will be releasing her next album with Universal-owned Decca Records in autumn 2014.
