Gossips in America are baffled after seeing BRITNEY SPEARS sobbing while taking a cellphone call.

The pop star broke into tears in the backseat of a car in California last week (ends12NOV04) and was caught distraught on camera by paparazzi.

But her representatives are refusing to comment on what upset the singer, who is rumoured to be pregnant with new husband Kevin Federline's baby.
