"In a passing moment last year, I let some words come out of my mouth that don’t reflect who I am, or what I stand for."

Mark Foster of Foster The People took to social media on Wednesday (April 10) to publicly apologize to Imagine Dragons frontman Dan Reynolds.

“I have been burdened by something I feel I need to amend,” Foster wrote in a lengthy note posted to the band’s official Twitter account. “I would like to apologize to Dan Reynolds and his band Imagine Dragons. In a passing moment last year, I let some words come out of my mouth that don’t reflect who I am, or what I stand for.”

Foster seems to be apologizing for a 2018 interview in which he joked that he and his bandmates gave all their subpar material left on the cutting-room floor to Imagine Dragons.

“Everything that I have read about what Dan is doing as a humanitarian is moving,” he continued, referencing Reynolds’ continued advocacy of the LGBTQ community and creation of Utah’s LOVELOUD Festival. “I believe he’s one of the good guys. It takes a lot of courage to stand for something...nobody has ever erected a statue of a critic.”

Foster signed off by promising Reynolds his support in the future, writing, “Keep fighting the good fight, Dan. You have my pledge to work alongside you if you ever need a hand. Much respect to you and continued success in your music.”

The apology comes weeks after Reynolds posted his own lengthy note on Twitter calling out Foster the People, as well as other bands like Slipknot and The 1975, for taking shots at Imagine Dragons in the press.
