Singer Amy Winehouse was admitted to hospital at the weekend, The Sun has reported.
The 26-year-old is reportedly experiencing more problems following her breast enlargement operation last October.
Amy was hospitalised in London after suffering chest pains, and kept in overnight while doctors carried out a series of tests.
She is understood to be waiting to hear if she needs to have her implants removed after already suffering complications in November.
"Amy was in agony and became convinced it was something to do with her boobs. She thought she would leave it for a while but the pain got worse," a source tells The Sun.
"She is waiting for a decision on whether the implants have to come out or not. Amy loves her curves and would hate to have to have them taken out. She is still her bubbly self but she is worried."
