Kim Zolciak's rich boyfriend DENIES estranged wife's claims of his 'out of control' spending on reality star

Kim Zolciak's boyfriend has strenuously denied his estranged wife's claims he has been overspending on the former Real Housewife of Atlanta.

Zolciak, 48, began dating real estate developer Kyle Mowitz in spring last year, in the midst of her increasingly rancorous split from former NFL player Kroy Biermann.

Mowitz is locked in his own divorce battle with his ex Jillian Greene, who is of the view that he has a sum north of $100 million held in a trust.

Greene has filed an injunction to put a stop to what she characterized as his 'out of control' largesse, for fear his fortune will be depleted once he has to split it with her.

Now Mowitz has fired back with his own court documents, firmly repudiating her 'repeated accusation' that he has been showering money on Zolciak, via TMZ.

He turned around and accused Greene of amassing debt on credit cards he funds, and of being so extravagant she once spent $2,300 on a hotel room.

Mowitz disputed his estranged wife's contention that his 'spending is out of control and that he fails to pay the expenses for his family and children.'

In his court documents, he held that it was 'plainly false to state that [Mowitz] uses his money primarily to pay for his own lifestyle and his girlfriend’s lifestyle.'

When Greene filed her injunction earlier this month, she insisted there was 'every reason to believe the millions of dollars' Mowitz stood to earn from his business 'will disappear quickly' because of his supposed generosity to Zolciak.

According to Greene, his munificence to his 'potential future wife' extended to covering her rent and legal fees, as well as furnishing her with a pricey car, bankrolling her travel and wine expenses and giving her loans.

Greene went as for as to subpoena Zolciak in the divorce case late last year, demanding that the reality star undergo a deposition and turn over information including her communications with Mowitz.

Earlier this month, Zolciak temporarily lost primary physical custody of her four children with ex-husband Biermann in a new ruling in their ongoing legal battle.

Court documents obtained by the Daily Mail show a judge granted Biermann’s emergency request regarding custody of their children - Kroy Jr., 14, Kash, 13, and twins Kaia and Kane, 12 - after he alleged Zolciak was 'unstable and unfit.'

Despite the decision, the former couple will continue to share joint legal custody, meaning both retain formal decision-making rights.

However, Biermann has been awarded final authority over major issues including education, non-emergency medical care and religious upbringing.

Under the arrangement, both parents will also maintain scheduled parenting time, with the children set to split time between households on alternating weekends.

Zolciak responded to the ruling in a statement to the Daily Mail, and also addressed the situation on her Instagram Stories days after the decision went public.

She began: ‘The senior judge’s (a 'retired' judge) decision from April 29th is temporary until we return to court as soon as possible when we will have the opportunity for a full hearing’

The message continue:, 'The new order was the result of an alleged emergency motion filed by Kroy to ensure the matter was heard by a senior judge instead of our duly elected assigned judge, who has never granted Kroy an immediate hearing despite him filing three separate (false) motions against me. 

'The decision rendered by the senior judge was largely the result of a flawed investigation by a guardian ad litem who has not spoken to me in over a year (until a brief call with me and my attorney on April 28th), or my oldest boys since July of 2025. 

'While I want this process to be over for my children more than anything, I am looking forward to a full court date when we will finally be provided with an opportunity to present the truth.’

The Daily Mail reached out to Biermann's representatives for comment.

The ruling comes amid escalating tensions between the former couple, with Biermann filing emergency motions in which he accused Zolciak of neglect and claimed she is prioritizing her public image and career prospects over the children’s welfare.

In his filing, he alleged she is 'more selfishly concerned with her own image and her work options' than their children's wellbeing.

The athlete also argued that all four children should be living under one roof, describing Zolciak as 'unstable and unfit' 

In addition to her sons and daughter with Biermann, Zolciak also has daughters Brielle, 29, and Ariana, 24, from previous relationships. 

The former Atlanta Falcons linebacker adopted them after tying the knot with his estranged wife in 2011.

According to court documents obtained by the Daily Mail, Biermann asked a judge to transfer custody to him, alleging his wife has been flouting her parental responsibilities. 

In a court paper, Biermann accused the media personality of 'blatant mismanagement of basic parenting responsibilities [that] would be practically unbelievable to anyone not familiar with the circumstances.'

Zolciak refuted the claims in a statement shared with the Daily Mail through a representative: 'These accusations are completely false and nothing more than a deliberate attempt by Kroy to defame my character. 

'I spent five weeks away working on two TV shows to support my family and make sure my children are cared for – something I will never apologize for.'

She added, 'I refuse to be bullied or have lies twisted into a narrative about who I am. I will not stay silent, the truth is on my side, and it will come to light – no matter how hard anyone tries to bury it.'

The latest development in the exes' divorce battle comes after they sat for a mediation session on January 27 to sort out their temporary child custody agreement.

Biermann claimed in his filing that his ex had been traveling extensively out of the country and failed to parent their children on their agreed-upon dates from February 26 through March 29.

He alleged in a court paper that the only exception during that period was when Zolciak exercised her parenting time on the night of March 9, when one of their 'minor children was subject to a dog bite.'

Biermann additionally alleged in a court document that Zolciak entered into their temporary mediated parenting plan 'in bad faith, knowing at the time of agreement that she could not and in fact did not intend to adhere to the terms of agreement.'

He also accused her of 'fraud and deceit' for pushing for the temporary agreement, which gave them joint custody.

The former athlete alleged that, when Zolciak was in the country and parenting on her assigned days, she allowed their children to miss their scheduled therapy sessions.

Furthermore, he claimed his ex failed to meet with her own therapist for the minimum required number of sessions, and accused her of 'lying to the therapists.'

Biermann claimed he was prepared to show, 'through expert and witness testimony,' that Zolciak is 'both unstable and unfit as a custodial parent,' and asked the court to immediately award him sole custody of their children.

The two Bravo stars have been separated since May 2023, with their prolonged divorce fight beginning in August 2023.
