The actor's ex-fiancee Brett Rossi, who has accused Sheen of hiding his HIV status from her during their 2014 romance, quit the porn industry in 2013, but she will be back in 2016.

Appearing on show The Single Life, Rossi confirmed the news and revealed she shot her comeback scene last week (ends11Dec15).

Telling host Sam Phillips it was "just like riding a bike", Rossi confessed she decided to return to porn because mainstream acting is "so boring".

The adult actress sued Sheen on 3 December (15), accusing him of failing to disclose he was HIV-positive before they had unprotected sex. In her lawsuit, she claims the former Two and a Half Men star was also verbally and physically abusive and asked her to have an abortion in March, 2014 due to health fears for the baby. She is suing for unspecified damages for claims including emotional distress, false imprisonment and negligence.

The actor's legal team has filed for a dismissal, declaring Rossi is "motivated by greed".

In the papers, obtained by The Hollywood Reporter, Sheen's lawyer Marty Singer states Sheen was never violent towards his former partner, but alleges Rossi "attempted to extort millions of dollars by disclosing Sheen's medical condition even though she had signed a confidentiality agreement."

Sheen revealed he was diagnosed with HIV in 2011 during a TV chat last month (Nov15), but Rossi maintains she had been having sex with the actor for several months, and only learned of his diagnosis after finding HIV medication in his medicine cabinet.

Sheen previously insisted he had informed every sexual partner about his HIV status before engaging in intercourse.

"Rossi is banking on the fact that Sheen will pay her millions of dollars to avoid the negative publicity surrounding this action," Singer states in the dismissal request. "Rossi was well aware of Sheen's medical condition and was the one who insisted upon having unprotected sex with Sheen."
