Pearlman was convicted in 2008 for his involvement in a massive Ponzi scheme that swindled 1,700 investors out of a half-billion dollars.

Pearlman was also sued by most of his acts — the Backstreet Boys, *NSYNC, O-Town, LFO, Take 5, Natural and Aaron Carter — for fraud and misrepresentation. Though, a few of his former clients have taken to Twitter to share their condolences.

“Word is that #LouPearlman has passed away,” Lance Bass tweeted on Saturday. “He might not have been a stand up businessman, but I wouldn’t be doing what I love today wout [sic] his influence. RIP Lou.”

“Mixed emotions right now, but RIP Lou Pearlman,” Chris Kirkpatrick wrote soon after.

O-Town’s Erik-Michael Estrada expressed similar sentiments.

“Mixed emotions,” he said.

Aaron Carter also took to Twitter to share his reaction.

“#LouPearlman my old manager died in prison… Rip Lou not the best business guy really at all but he did discover me,” he wrote. “Karma is real.”

Justin Timberlake offered his condolences. “I hope he found some peace,” he wrote. “God bless and RIP, Lou Pearlman.”
