In September, 2016, less than a year after their South Beach ceremony, he married Shannon's daughter, splashing photographs from their nuptials on social media to the horror of his devastated former wife.
Kaylee refused to speak to DailyMail.com on Wednesday, replying 'no comment' when asked why she had married her mother's husband.
Still reeling from her daughter's betrayal, Shannon said she was devastated to have to relive it through Hauptmann's pending criminal case.
Kaylee and Christopher live together in Shamokin one mile away from her mother's house and run PA Bail and Recovery together.
Shannon claimed she is taunted by the pair about their new relationship and that Hauptmann has sent her photographs of them having sex.
She believes their affair began while he was living with her and her daughter in the family home but she was unaware of it when she left him.
While they were still living together, Hauptmann took her daughter to concerts in other states without her permission when she was still a minor.
She claims he forced her to dye her hair blonde to resemble her and says he 'brainwashed' her daughter.
Her other daughter Courtney, once inseparable with Kaylee, said it was a difficult time for the family.
Kaylee answered the company's phone on Wednesday while her husband remained behind bars.
She refused to speak about their marriage or her family who have disowned her since she fled the home last September.
Her mother fears she has been 'brainwashed' by Hautpmann.
On social media, she gushes over Christopher and their new life together. 'Spending quality time with my amazing husband. Loyalty and dedication.
'Till death do us part,' she wrote alongside a recent selfie of them cuddled up in bed.
After their wedding in September, Christopher shared photographs of their rings and glasses of champagne on Facebook.
Hauptmann is facing four felony charges for possessing a gun as a convicted felon alongside one count of misdemeanor of bigamy.
He failed to meet his $300,000 bail on Tuesday and is awaiting his next court date.
