Report: Britney Spears is pregnant

Friends of Britney Spears have apparently told an Australian magazine the star is pregnant with her third child.

According to the sources, the 25-year-old, who recently split up with husband Kevin Federline, has recently learned the surprise news.

A source told NW magazine: "She's been secretly filling her pals in on the good news since last week. Britney is in shock herself, this definitely wasn't planned. She's thrilled just the same."

Spears, who had sons 22-month-old Sean Preston and 10-month-old Jayden James with Federline, has been linked in recent months to former lover and counsellor John Sundahl and bodyguard Daimon Shippen.

Meanwhile, gossip website TMZ says Spears was "completely out of it" during a recent interview with the US OK! magazine.

She is said to have personally agreed a deal with editor Sarah Ivens before giving an erratic, paranoid interview and posing for terrible photographs. Magazine bosses are apparently unsure what to publish.
