Troubled star Amy Winehouse reportedly checked into a London clinic on Saturday, complaining of pain from a recent breast enhancement surgery.

The singer was said to have undergone an uplift procedure to boost her assets on Wednesday in a bid to look her best while performing on TV contest Strictly Come Dancing at the weekend.

But the Rehab hitmaker was in agony as she sang back-up vocals for goddaughter Dionne Bromfield - and demanded to see a doctor as soon as filming ended.

A source tells the Daily Mirror, "Amy started shouting, 'I need to see someone, my boobs are f**king killing me.' Her manager quickly sorted a car to get her to the London Clinic. Typically, Amy made the driver stop off at Nando's (restaurant) for some chicken - she said she didn't want hospital food.

"The doctors ordered her to stay overnight to make sure everything was OK. She only had her breasts lifted a few days ago and she should have been resting to let them heal instead of running around town.”

The publication alleges Winehouse was discharged on Sunday.
