Diddy has shared a touching tribute to Chucky Thompson after it was reported that the 53-year-old producer tragically passed away. Thompson was one of Bad Boy Records’ in-house producers, dubbed “Hitmen,” and had credits ranging from The Notorious B.I.G.’s “Big Poppa,” Faith Evans’ “You Used To Love Me” and Mary J. Blige’s Grammy-nominated album My Life.

“I’ve been in shock most of the day. Chucky Thompson was not just someone that I made Mary J Blige’s My Life with and a part of the legendary Hitmen, he was also one of the greatest humans that I’ve ever met,” Diddy captioned a post on Instagram on Monday (Aug. 9). “He always kept you laughing, always kept you smiling and he always let you know that he loved you. I love you Chucky. One of the greatest of all time. You will be truly missed.”

In her own Instagram post, Blige also remembered the hitmaking producer.

“Damn! I just spoke to this man last month! We were discussing our plans to work together again,” she wrote. “Chucky and I was and will always be a musical match made in heaven. He knew everything I was feeling personally and when we worked on the My Life and Mary albums. He was an angel sent to help me weather my storm. Now my brother and my friend returned to where all angels and beautiful people like him come from. RIP to one of the best who’s ever done it. This is soooo sad. Too many people leaving too soon.”

As reported by REVOLT, producer Young Guru first revealed Thompson passed away on Monday. In an Instagram post, he called the legendary producer, “My mentor, my big brother [and] the man who changed my life forever.”
