Reports emerged earlier this week that the Anger Management star and his former spouse had been seen partying in Los Angeles together, prompting a return for Mueller to rehab.
Mueller has since refuted the claims, saying that she is still clean and merely returned to rehab for a pre-scheduled court order.
According to TMZ, Sheen has now issued a statement in regards to the reports that reads: "I can't speak to anyone's opinion or judgement. I was there, they were not.
"Their tepid hearsay is a baseless static drone. A mantra. Their theme. I refuse to be held hostage by their 'constitutional' privelidge (sic) to judge those who can and who do."
However, he has yet to formally confirm or deny the allegations.
Sheen's new TV show Anger Management premieres June 28 on FX.
