Britney Spears has reportedly stood up Madonna so she can spend some quality time with her sons Jayden James and Sean Preston.

The singer – who has been granted custody of her two boys for the period leading up to Thanksgiving – has bailed on a performance with Madge in Miami.

A source tells The Sun, “Britney had always agreed to perform in Miami but her circumstances have changed over the past couple of months.

“She and Kevin are getting along fine now, Britney will have Jayden and Sean just before the holiday and Kevin will spend Thanksgiving day with them.”

Britney is following up her holiday at home with an appearance in the UK on the X Factor on November 29.
