Most of the time, chest pains are no laughing matter. In this case, though, they kind of are. Because it's Amy Winehouse and they're not even heart-related.

The deeply troubled songstress was was admitted to a hospital after reportedly experiencing agonizing pains from her breast implants on Thursday night.

We hope you weren't eating while reading this.

The 26-year-old is now said to be waiting for a decision on whether she needs to have the 32D implants removed, or must undergo corrective surgery.

Amy Winehouse was previously treated by medics in November after experiencing complications following her breast enhancement, as her dad told us.

Guess this rules out the potential ass implants.

COVERED UP: Amy Winehouse looking remarkably normal.

"Amy was in agony and became convinced it was something to do with her (breasts),” a family friend said. “She thought she would leave it for a while but the pain got worse. She went into the clinic on Thursday and is under observation."

"She is waiting for a decision on whether the implants have to come out. Amy loves her curves and would really hate to have to have them taken out."

"She is still her bubbly self but she is worried."

The Black to Black Grammy winner star paid $54,000 last October to restore the curves she boasted before she developed her death-defying drug habit.

Since having the operation, she has been regularly showing off her eye-popping bust ... which we're sure Blake Fielder-Civil hopes she will retain.
