Susan Boyle blames her single status on her Catholic parents' ''coded behaviour''.

The 'Wild Horses' singer has revealed her mother and father's strong Christian beliefs have affected the way she approaches romantic relationships as an adult.

Susan, 53, said: ''My parents were stalwart Catholics, and there was a kind of coded behaviour I had to keep to - that's why I'm still single. Simply put, the right guy hasn't come along yet.''

Susan is open to a relationship and still dreams of one day having her own family.

She said: ''It would be nice to have somebody in my life, as I'd like to have a baby, so I'll just keep waiting. In the meantime, I have 16 nieces and nephews - plenty to occupy me with. If God wants it to happen, it will.''

Susan credits God for giving her the vocal ability that has made her a star since she finished as a runner-up on 'Britain's Got Talent' and says she is still a very religious person.

She said: ''God must think singing is good for me. My faith is important to me, my favourite saint is St. Bernadette. She was from a poor background and raised to a high position, spiritually. I feel an affinity to her, though not on her level...''
