Ryan Reynolds has apologised for choosing a slave plantation in South Carolina for his 2012 wedding to Blake Lively.
In an interview with Fast Company, Reynolds called the decision to wed at Boone Hall "a giant f**king mistake", adding that he still felt shame over it.
Last year, both Pinterest and wedding planning website The Knot both banned pictures of the wedding venue after a civil rights advocacy group wrote to them saying plantation venues with a history of slavery should not advertised as inspiration online.
"It's something we'll always be deeply and unreservedly sorry for," he said.
"It's impossible to reconcile. What we saw at the time was a wedding venue on Pinterest. What we saw after was a place built upon devastating tragedy."
The Hollywood power couple later got married again at home, but "shame works in weird ways", according to Reynolds.
"A giant f**king mistake like that can either cause you to shut down or it can reframe things and move you into action," he said.
"It doesn’t mean you won’t f**k up again. But repatterning and challenging lifelong social conditioning is a job that doesn't end."
In the wake of George Floyd's death and the Black Lives Matter movement, Reynolds and Lively donated US$200,000 to the NAACP and released a statement about combating systemic racism.
"We're ashamed that in the past we've allowed ourselves to be uninformed about how deeply rooted systemic racism is," they said, adding "we've been teaching our children differently than the way our parents taught us".
