Washington, November 19 Amy Winehouse's father Mitch has revealed that she had problems with her recent boob job which prompted her stay in hospital.

Earlier reports had suggested that the singer entered The London Clinic in the U.K. capital after suffering an adverse reaction due to cold medication.

"It wasn't because she has a cold. She's fine, she just had a little leaky something or other," Contactmusic quoted him as saying.

Also, a friend told Britain's Daily Mirror newspaper: "She saw something oozing out on to her top. She was worried as to see stuff seeping out was horrible."

Winehouse had undergone a breast enhancement operation in October. (ANI)
