Is Brooke OK? Mueller's Parents Rush To Utah After Hospitalization

Brooke Mueller's parents rushed to Utah after her hospitalization, RadarOnline.com has learned.

"I know that my mom is with Brooke right now in Utah with the boys," Mueller's sister Sydney Wolofsky told RadarOnline.com exclusively. "Both my parents are there with them."

Sydney noted that they arrived yesterday, but it was unclear if they went straight to the hospital or to Mueller's home.

Sgt. Todd Royce of the Utah Department of Public Safety told RadarOnline.com last night that, "On the morning of November 16, dispatchers with the Utah Department of Public Safety received a welfare check call from a woman claiming to be the mother of Brooke Mueller. Troopers with the Utah Highway Patrol responded to the welfare check call and located Mueller, her two children and a nanny on Interstate 15 near Nephi, Utah."

He added that 7-year-old twins Bob and Max would be released to family during 39-year-old Mueller's hospitalization.

Charlie Sheen's ex's sobriety was first called into question after she allegedly got into a fight with her children's nanny at a bar. She was barefoot, and left before the cops arrived. She was later spotted in another argument at a local gas station.

Still, Sydney insisted to RadarOnline.com that Mueller has been sober since her rehab stint earlier this year, and that she was "totally coherent and everything" during their Tuesday afternoon chat.
