Rumour has it that Pink�s marriage to motocross star Carey Hart is in trouble after just a year.

The wild couple married in Costa Rica last January, but spending long periods of time apart is said to have put a massive strain on their relationship.

A source told the National Enquirer: "Pink and Carey's marriage is in trouble.

"They're both crazy busy with their separate careers, and it's beginning to take a toll on their relationship.

"They're hardly ever together."

Pink has been on a world tour promoting her latest album �I�m Not Dead� while Hart has been busy running his tattoo parlour and riding his bike.

Hopefully they can work it out�
