Britney Spears is reportedly pregnant with her third child, sources claim.

The TOXIC singer, who has been in and out of rehab over the last few months, has told close friends that she is pregnant, according to NW magazine.

However, it also claims Britney is unsure who the father is.

A source said: "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."

Two men are currently in the frame to be the father: John Sundahl, Britney' former lover and drug counsellor while she was in rehab, and Damion Shippen, the pop star's bodyguard.

Britney currently has two children from former husband KEVIN FEDERLINE, one-year-old SEAN PRESTON and ten-month-old JAYDEN JAMES.

Meanwhile, the former pop princess is determined to set the record straight with a tell-all interview in OK! magazine.

Britney apparently called up the publication herself and offered the interview, which could be part of her attempts to reignite her fallen career.
