The 32-year-old singer, who is also a judge on reality television show Strictly Come Dancing, said that she doesn't know why she never has a boyfriend.
Dixon told the Daily Star Sunday: "I guess I'm just unlovable. I can't remember the last time I had a boyfriend. But having said that I'm happy. I have had my head down and am focused on work but I'm waiting for a special guy to grab my attention."
The star used to be married to So Solid Crew's MC Harvey, but ended their marriage in 2006 after discovering he was having an affair with singer Javine Hylton. She has since admitted that she is too busy for love.
Dixon recently revealed that she would adore seeing one of the couples from this year's Strictly Come Dancing fall in love, saying: "I'm sure there will be a romance because there has been every year. The dancing is so intense and passionate it just happens.
"I don't know who it will be but I'd bet money that there is some sort of affair. You spend so much time with each other it always seems to happen. The thing is I don't think anyone is single so that could make for an interesting show."
