Washington, If reports are to be believed then Britney Spears will soon be changing diapers once again.
A source has revealed to NW magazine that the singer is pregnant with her third child.
And though Britney is said to be very happy about the news that has come as a bit of a shock, the source also revealed that she doesn't quite know who the baby's father is.
"She's been secretly filling her pals in on the good news since last week," Contactmusic quoted the source, as telling the mag.
"Britney is in shock herself, this definitely wasn't planned. She's thrilled just the same," the source added.
The two men who are being seen as possible contenders for the title of Britney's baby daddy are John Sundahl, Britney' former lover and drug counsellor while she was in rehab, and Damion Shippen, her bodyguard.
She already has two sons - Sean Preston and Jayden James - from estranged hubby Kevin Federline.
