Britney Spears is expecting a baby with music producer J.R. Rotem, according to reports.

Rotem allegedly confirmed the news of the singer's third child by telling In Touch Weekly: "It's true."

According to the magazine Spears revealed that she was four weeks pregnant to friends on November 14 and emailed her ultrasound scan to them.

The star is currently involved in a custody battle with ex-husband Kevin Federline over their two boys Sean Preston and Jayden James.

Spears has reportedly been having an on-off relationship with Rotem since she split up from Federline last year.
