A MALE escort claims he had a ten month affair with evil dad Chris Watts during which the killer paid for his lip fillers.
Trent Bolte, 28, said he had a secret fling with the dad-of-two that ended shortly before Watts, 33, murdered his pregnant wife and two young daughters.
He told cops they stayed together at a remote Wyoming cabin, something his mum Colleen has confirmed, according to reports.
The Daily Mail reports she said Watts had given her son money and even paid for him to get lip injections.
Bolte's story was initially thrown into doubt after he first claimed to have been with Watts in a Facebook post after the murders.
But his mum told investigators Watts "paid him $250, $80, and $60 on separate occasions".
She said that her son 'admitted he was seeing Watts long before the horrible crime', according to The Daily Mail.
Bolte wrote in a Facebook post in August: "We had relations off and on from last June up until March or April. I found out he was married with kids in February. I didn’t know that when we first met, said Bolte in that post.
"I can only speak for myself but before this happened, I would’ve 100% told you that Chris isn’t a murderer nor a sociopath.
"He told me he was the victim of emotional and mental abuse and was stuck in loveless marriage but was so scared to leave because of Bella and Celeste."
Evidence of Watts' rocky relationship with wife Shanann has already been revealed in texts between the pair.
The messages are contained in documents, which also include an interview with the triple murderer's lover, Nichol Kessinger.
Watts was sentenced to life in prison on for murdering his pregnant wife Shanann, their daughters - four-year-old Bella and three-year-old Celeste - and unborn son Nico.
A report reveals how Shanann filmed a video revealing her third pregnancy to Watts - a clip which doesn't appear to show any sign of problems in the relationship.
But messages sent about three weeks later suggested their relationship was falling apart.
According to the report, one message Shanann sent to Watts read: "How can you sleep? Our marriage is crumbling in front of us and you can sleep."
His mistress Kessinger told police that Watts was struggling with finances, and that she did not know if he could afford another kid.
In her interview, Kessinger said Watts and Shanann, 34, "did not get along well" and that the couple's financial life was "troubling".
Investigators wrote: "She said Chris was struggling with finances and now he had a third kid on the way and she does not know if he could afford another kid.
"Shanann was not responsive to this financial trouble. Nichol said Chris always told her he wanted a third child and wanted a boy."
Shanann’s father, Frank Rzucek, told the court his pregnant daughter and granddaughters’ lives had been taken by an “evil, heartless monster” who “took their bodies out like the trash”.
He added: “God only knows what happened that night but life will never be the same. They had all their lives to live.
“They were taken by a heartless one, taken by an evil monster… You took them out like trash, you disgust me.”
