AMY WINEHOUSE HOSPITALIZED FOR CHEST PAINS!

Just as Amy Winehouse cleans up her act, the "Rehab" singer was back in the hospital over the weekend – but not for the reasons most would suspect.
According to People.com, the 26-year-old singer was experiencing chest pain and discomfort in the breast implants she had put in last fall.

"She had them checked out and all was OK, so she didn't have to stay in," a friend told the mag.

Following last year's surgical procedure, Winehouse's father, Mitch, boasted that his famous daughter's breast enhancements were "fantastic."

"Fantastic, fantastic. Her boobs are great as well," Mitch said on British TV show "This Morning." "I shouldn't have said that should I? She looks absolutely fantastic."

Winehouse was last hospitalized in November, after having a bad reaction to mixing over-the-counter medication with other medications.
