Amy Winehouse's stay in the hospital earlier this week was prompted by problems with her recent boob job, according to her father Mitch.

The Back To Black hit-maker entered The London Clinic in the U.K. capital on Sunday, reportedly due to an adverse reaction she suffered after taking medication for a cold.

However, her dad Mitch has admitted she actually entered the facility because of complications from her breast enhancement operation in October.

He says, "It wasn't because she has a cold. She's fine, she just had a little leaky something or other."

A friend explains to 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."
