Amy Winehouse may be getting her life back together – but one of her newest enhancements landed her in the hospital briefly Saturday.
The 26-year-old singer was experiencing chest pain and discomfort in the breast implants which she had fitted last fall. “She had them checked out and all was OK, so she didn t have to stay in,” a friend tells PEOPLE.
Winehouse was last hospitalized in November following a reaction involving over-the-counter medication that mixed with other medication in her system.
