John Mayer stopped his concert mid-show over the weekend after a fan seemingly invited him to a hotel room. The pop star was on stage in Long Island on May 7 in the middle of his Sob Rock tour when he pointed out that someone made "a makeshift sign on their iPhone" that read "Room 2307." "That's all it said. That's all the information I was supplied with," he added, according to Page Six.The Grammy winner then had a whimsical take on the situation."In the back of my mind I was thinking I'd have to go to every local hotel — I'd assume it would be a hotel — knocking on the door of 2307 until I found the person who had the sign '2307,'" he said.
