Just 24 hours after losing visitation rights to see her two sons, Britney Spears had the rights reinstated - but then skipped a session with her court-appointed parenting coach.

Britney lost access to sons Sean and Jayden on Thursday after failing to comply with previously stipulated criteria - specifically, not providing the Los Angeles Superior Court with correct contact details to enable them to carry out mandatory drugs testing.

The visiting suspension was revoked on Friday after Britney provided the court with the details but she is said to have put her access at risk again after skipping out on the coaching session.

According to the Sun, Britney was set to meet with the counsellor at her Malibu home on Friday afternoon for one of her court-mandated twice weekly session but when the coach arrived, Britney was nowhere to be found.

Yesterday, Britney was spotted driving with her children near Studio City in Los Angeles with a court-appointed supervisor also in the car.

Britney and ex-husband Kevin Federline are both expected to appear in court on Friday for the next scheduled hearing in their ongoing custody battle.
