Singer Bret Michaels has abruptly ended a concert in New Hampshire after suffering a medical emergency.

Guitarist Pete Evick says on Michaels' Facebook page that Michaels was three songs into his set in Manchester on Thursday when he rushed from the stage. A crew member reported that the former Poison lead singer's blood sugar was extremely low. Michaels was diagnosed with Type 1 diabetes as a child.

Evick says Michaels returned to the stage, telling fans he couldn't continue. Evick says when he went to the band's bus to check on Michaels, "he could barely speak, but begged me to apologize to the fans."

Michaels thanked the paramedics on Twitter and Facebook who provided assistance.

Michaels won the 2010 "Celebrity Apprentice," raising money for the American Diabetes Association.
