AMY WINEHOUSE's stay in hospital earlier this week was prompted by problems with her recent boob job, according to her father MITCH.
The singer 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.
But 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."
