Amy Winehouse's ex-husband has told her to go to rehab.

Blake Fielder-Civil - who reunited with the 'Back to Black' singer earlier this year - has reportedly told her to seek help for her alcohol addiction before he will consider marrying her again.

A source told Britain's The Sun newspaper: "Amy is always telling Blake she wants to get married again but he's saying not until she cleans up her act."

Meanwhile, Amy has reportedly spent £70,000 staying in a hotel for just 10 days.

The 'Rehab' singer has astonished staff at London's upmarket Langham hotel with her extravagant spending, insisting on staying in a plush suite containing an infinity pool and two bedrooms while waiting on the results of a survey being carried out on a property she is planning to buy.

A source said: "Amy's waiting to get the go-ahead on her new home in Camden, north London, the mortgage agreements and surveys haven't been finalised so she's staying in a hotel in the interim.

"She has lavish tastes and is hiring a superior two bedroom suite for herself and her security team.

"The suite is decked out with flashy furniture, a four-poster bed two dressing rooms, a lobby with a cloak room and a magnificent infinity bath."

In addition to a suite for herself, Amy also purchased rooms for her pals so she wouldn't feel lonely during her stay.

The source added to the Daily Star newspaper: "She hates being alone so invited friends to come and keep her company, ordering endless stuff from the room service menu including drinks from the posh cocktail bar, which specialises in rum-based cocktails."
