Britney Spears is reportedly back in Promises rehab centre less than 24 hours after checking out (yes, you read that correctly - this the THIRD time this week she's hit up a treatment clinic).

According to reports breaking in the US, the singer checked back in this morning (February 22) after crisis talks with her ex, Kevin Federline.

As a result of her decision to get help, K-Fed has agreed to cancel today's emergency custody court hearing.

Further US reports claim the singer made a desperate visit to her former hubby's house in the early hours of this morning in a bid to make him change his mind about the case.

This is allegedly Brit's last chance to clean up her act as far as Fed's concerned.

Crikey. We can't keep up, dunno about you?
