TMZ first reported the news. Lima was 41.

Lima, whose birth name was Harold, was a member of the three-man boy band LFO, well known for its 1999 single “Summer Girls.”

People reported that the singer had surgery to remove a tumor in October 2017. A week after the surgery, LFO bandmate Brad Fischetti said Lima had stage 4 adrenal cancer.

"Devin asked me to give you this update without him because, frankly, he's not feeling very well, but he asked me to send you his love and gratitude for all the love and prayers you've sent his way," Fischetti said in an Oct. 30, 2017 video. "He's had a tough recovery and a few really difficult days in the hospital, but thankfully he's home now resting and healing. The pathology report came back and unfortunately it confirmed cancer."

This is the second death in the band. Singer Rich Cronin died of leukemia at age 35 in 2010.
