Britney Spears has sparked reports she is pregnant with her third child, after the troubled star was spotted shopping for home pregnancy tests in Los Angeles recently.

The pop star had visitation rights for her sons suspended after her bizarre stand-off with emergency services at her Los Angeles home earlier this month, which occurred when she failed to hand over one-year-old Jayden James to ex-husband Kevin Federline's employees following a scheduled visit.

But Spears appears to be getting serious with her paparazzo boyfriend Adnan Ghalib, after she was snapped browsing pregnancy tests at pharmacy store Rite Aid earlier this week.

The singer was forced to deny reports she was expecting producer Jonathan 'J.R.' Rotem's baby in November, after an apparent confession appeared on a private MySpace page, allegedly belonging to the star.
