LOS ANGELES (AP) _ Prince has disappeared from Twitter and Facebook. Billboard reports the Twitter account for Prince/3rdEyeGirl, his backing band, has been deleted, as has Prince’s Facebook page. Prince’s first tweet was a test tweet, then his second one read, “Prince’s Second Tweet,” then his third was a photo of a salad smothered in pepper. Most of the other tweets were related to 3rdEyeGirl. Prince held a Facebook chat last month in which he answered one question in three hours.
