Britney Spears has given birth to her second child in the US according to MTV News, but there was no immediate confirmation from representatives for the singer and her husband Kevin Federline.
A source close to the family told MTV News that the pop star had the baby late on Monday night.
But the report said whether it was a boy or girl had yet to be officially revealed.
Spears confirmed her pregnancy in early May during an appearance on The Late Show With David Letterman.
She and Federline already have a baby son together, Sean Preston, born on September 14, 2005.
Spears told People magazine in August that the new baby and its big brother “are going to be so close together, it’s going to be weird. But I love it,” she says.
