Who are the celebrities involved with Ashley Madison?

Ashley Madison, the infamous dating website geared towards people seeking extramarital affairs, was hacked in 2015, leading to a massive data breach. The leak of confidential user information caused a scandal because it revealed the identities of individuals who had signed up for the service. However, due to the discreet nature of the site and the privacy concerns surrounding it, there has been limited confirmation of specific celebrities involved. While numerous media outlets and internet discussions have speculated about celebrity involvement, concrete evidence linking specific public figures to Ashley Madison accounts was not widely divulged, in part because any such association could be damaging to reputations and because verifying the accuracy amid potential false accounts was complex.
