“The boys are with me now and they are doing great,” Mueller’s mom, Moira Wolofsky Fiore, exclusively tells PEOPLE of last week’s incident. “They are both in school here in Utah.”
On Tuesday night, Mueller, 39, walked into a Salt Lake City bar barefoot with her sons and the nanny, according to TMZ. While in the bar, Mueller and the nanny reportedly got into an argument, prompting a bystander to call the police.
According to Fiore, Mueller — who has struggled for years with substance abuse and mental health issues — has physical custody of sons Bob and Max while sharing legal custody with Sheen.

“Charlie is happy when he is with the boys, and when he is not with them, he talks to them nightly before they go to sleep,” Fiore says. “The boys are fine.”
Despite Mueller’s ups and downs, Fiore tells PEOPLE that the boys’ “lives are good.”
