The woman who claimed to have 'fallen in love' with Graham Dwyer has been banned from prison visits because of her choice of clothing.
Victoria Andreenkova, who lives in Dublin but is originally from Russia, was issued a visit ban from prison authorities.
It was feared convicted killer Dwyer may have been advising her on what to wear during prison visits, the Irish Daily Star reports.
Andreenkova, who attended the Dwyer's trial at the beginning of the year, has been told that prison authorities are keeping a close eye on any future attempts to visit the medium security Midlands Prison in Portlaoise
Andreenkova claimed at the weekend she is in love with Graham Dwyer.
She also previously made claims that a garda was responsible for murdering Elaine O'Hara and contacted gardai just before Dwyer's trial to claim the officer had killed the childcare worker.
The 37-year-old says she began a relationship with Dwyer after she started visiting him in the Midlands Prison following his conviction.
The pair first grew close after Andreenkova, who is a mother, contacted Dwyer to tell him she believed he was innocent.
She claimed a rural-based garda was responsible for Ms O'Hara's murder, and said she did not want to comment on her relationship with the killer, but did admit she'd changed her Facebook status to 'In a relationship'.
"I'll have to ask Graham first, if he thinks it's okay or not. I don't know what to say," she said.
Andreenkova previously made headlines after other allegations against a second garda.
An investigation was launched by the Garda Ombudsman Commission (GSOC) in October 2013 after she claimed she came under pressure to take abortion pills bought online by a senior garda officer.
She told GSOC she became pregnant after a brief tryst with the officer in a car in Ballymun.
It was claimed that the married garda bought illegal abortion pills on the internet and asked that she take them.
She said she pretended to take the first of five abortion pills when she met the officer in Dublin city centre after she told him of her pregnancy.
And she claimed she kept the pill in her mouth while pretending to swallow it.
Andreenkova alleged in her statement that she felt intimidated by the garda and that he threatened her with deportation when she refused to have an abortion.
Despite an extensive GSOC investigation, the garda watchdog has failed to either bring charges against the officer in question or to clear his name.
Andreenkova last year rang Taoiseach Enda Kenny to report her 'breast pump' had been stolen by Fine Gael.
During the call, Mr Kenny was left speechless after he was told a Fine Gael party member stole the pump.
"I am very, very angry at your government because a Fine Gael member stole it," she said.
Architect Dwyer (42) was found guilty in March of murdering childcare worker Elaine O'Hara on August 22, 2012.
