Scheana Shay said her ex-husband "deserved" to get $50,000 in their divorce settlement.
"It was very amicable and as much as I didn't want to give $50,000 to a person with a drug problem, he deserved it for just being a part of the show for so long and my life and my story," Shay said.
"I'm like, 'Look, I'm not trying to, like, cut you out and leave you high and dry, so here's how much we have. Is this okay?' and he agreed," she added.
"I just hope he's doing something useful with it and not just wasting it."
TMZ reported Friday that Shay will keep two cars, a bank account containing $1,000 and a retirement fund worth $31,000, while Mike will receive $50,000 and a 2005 GMC Sierra.Shay filed for divorce in November after two years of marriage.
"There were a lot of things from the beginning of our marriage that kind of tainted the whole relationship. Three months in, I found out he had a pill problem," she told E! News in March.
Shay is known for starring on "Vanderpump Rules," which completed a fifth season on Bravo in April.
The show follows "The Real Housewives of Beverly Hills" star Lisa Vanderpump and the staff of her restaurant SUR.
