Third Eye Blind frontman Stephan Jenkins is singing his praises for Machine Gun Kelly. "He's such a genuine, open-hearted person," Jenkins, 60, exclusively shared with Us Weekly as Instacart and Third Eye Blind prepare to host a New York City concert on September 4. "You meet him, and it's like you're really getting the real thing. He's sincere, and there's just this genuine feeling that rolls with him." Jenkins had the opportunity to meet up with MGK (real name is Colson Baker) as he worked on his new album, Lost Americana.
