Amy Winehouse has been spotted around with a large mark on her cheek, and her publicist has confirmed that Winehouse has a rare skin condition.

"Amy has been diagnosed with impetigo which she's been told can be highly contagious. Because of that she's been put on antibiotics and may have to stay home alone for the next few days."

According to the MayoClinic.com, "Impetigo starts as a red sore that quickly ruptures, oozes for a few days and then forms a yellowish-brown crust that looks like honey or brown sugar. The disease is highly contagious, and scratching or touching the sores is likely to spread the infection to other parts of the body as well as to other people. Impetigo is seldom serious, and minor infections may clear on their own in two to three weeks."

Winehouse may have contracted impetigo by not washing her face properly or by not caring for marks and cuts on her face.

No kisses on the cheek for you!
