The actor went public with his HIV-positive diagnosis during a candid U.S. TV interview on Tuesday (17Nov15), revealing he was coming forward with the news in an effort to stop ongoing extortion attempts from ex-lovers.
But it now appears he could be facing more pay-outs from a group of women, who have asked Allred to represent them.
They all claim Sheen put them at risk by sleeping with them.
"Since Charlie Sheen's interview, I will now confirm that I have been contacted by women with reference to Charlie Sheen and their rights," Allred tells TMZ.com. "I have no comment on what will happen next."
In his interview with Today show host Matt Lauer, Sheen insisted he has told every woman he has slept with following his HIV diagnosis in 2011 that he had contracted the disease.
Former porn star Bree Olson and a host of other women have already come forward with claims they weren't told Charlie was ill while they were sleeping with him. Sheen's representative insists that's because his client did not know he was HIV-positive at the time.
Sheen has confessed that he had unprotected sex with two women post-2011, but insists both knew of his condition.
Allred has had a busy 2015 - she has been representing 28 of the 40-plus women who have hit funnyman Bill Cosby with accusations of sexual abuse, rape and drugging. She recently deposed the comedian on behalf of one of her clients.
