Chet, who has been candid about his struggles with substance abuse, revealed the information in an emotional video on Instagram.
"I know I've been not that active on the 'Gram lately because I've been figuring out my life, which is what we're all doing, and social media's all bulls--t anyway. With that being said, I want to share something today because it's about to be shared anyway in the press, which is the fact that I have a daughter," he said in the video. "I do have a daughter. She's the best thing that's ever happened to me."
