Bedingfield recently spoke about her relationship to Us magazine.

'What should I say about him?' she said. 'I'm in love!

'He's a businessman and it really is a good balance for my career because he's always a solid rock that I just feel very comfortable with, and I feel very loved.

'I was single for a long, long time and I kind of went down kicking and screaming because I liked my single-ness, but he was someone definitely worth giving up being single for.'
