There were plenty of doctors in the house, but unfortunately for a dinged-up Natalie Cole, they were all fake.

The 55-year-old "Unforgettable" Grammy winner slipped and broke her arm on the set of Grey's Anatomy last week, Cole told E! Thursday night at a Los Angeles party.

Cole had been filming a guest spot on the hit ABC drama at the time of the accident.

With her anatomy in disrepair, and nary a real medic to take care of her, the able-bodied faux staffers of Seattle Grace managed to call 911 and have an ambulance take Cole to a nearby hospital. She was patched up and pronounced well enough to return to the Los Angeles set, where she completed shooting on her scenes.

An ABC spokeswoman declined to comment on the nature of Cole's role, but did say the singer-actress would appear in one of the final episodes of the season.

Cole is the latest guest star to check in to Grey's Anatomy, which has become one of the top shows on television both critically and ratings-wise during its season and a half. The series was nominated for a Golden Globe for Best Drama Series in January, with costar Sandra Oh claiming the prize for Best Supporting Actress. Grey's Anatomy is the fifth-most watched series this season, averaging about 20 million viewers per episode, per Nielsen Media Research.

Having her arm in a sling hasn't kept Cole from hitting the party circuit. Aside from showing up at a pre-Oscar party Thursday in L.A. sponsored by Los Angeles Confidential magazine, she appeared in Beverly Hills last week for Star Jones Reynolds' new book, Shine, according to the The Insider.

In addition to her Grey's Anatomy foray, Cole is coming off a lifetime achievement award at last year's 36th Jazz and Heritage Festival in New Orleans. She has also been working on a follow-up to her most recent album, 2002's Ask a Woman Who Knows.
