The former wife of Charlie Sheen is currently being treated at the Betty Ford Clinic for her addiction issues and will be allowed to see her children for a few hours, reported Radar online.
This will be the first time Mueller has seen her sons since she was admitted to rehab for the 20th time on May 1.
The children are currently being looked after by Sheen's other ex-wife Denise Richards, even though Brooke recently tried to have them removed to the care of her brother.
Mueller, who would have retained the USD 55,000-a-month child support she receives from ex-husband Sheen if her brother was caring for the boys - had alleged Richards had only agreed to take on the children for her own financial benefit.
Besides caring for the twins, Richards, 42, also has daughters Sam, nine, and Lola, seven, from her marriage to Sheen, and adopted little girl Eloise, 23 months.
