We had never really heard of Melendi, but apparently the Spanish singer is a big-time necio: He caused so much drunken ruckus on a flight from Madrid to Mexico this week that the pilot had to turn the plane around and return to Spain! The worst part: The plane had already been en route for three hours. Imagine being on a plane for six hours only to end up back where you started? No word on whether fellow passengers tried to jump ese Melendi upon landing. (News via latingossip.com.)
