Britney Spears wants to marry again in "five years" time.

The 27-year-old singer - who is divorced from second husband Kevin Federline, and had her 2005 marriage to Jason Alexander annulled after just 55 hours - is keen to wed for a third time despite her bad experiences.

She told America's Glamour magazine: "In five years I would like to be married and have a father figure for my kids, someone who is a provider and can be really stable."

Britney - whose sons Sean Preston, three, and Jayden James, two, live with their father Kevin - also appeared to blast the rapper's parenting ability, adding: "It's hard doing it on your own."

The "Womanizer" singer revealed she finds it hard to be taken seriously, because people can't look beyond the public breakdown she suffered earlier this year.

Britney - who was hospitalised after refusing to return her children to Kevin in January - said: "When I tell people the way I feel, it's like they hear me, but they aren't really listening. It's bad."
