The 'One Sweet Day' hitmaker gets massages, full body wraps, manicures and facials for her precious pooches, reported Daily Mirror.
"Mariah pays for all the spa therapies herself and doesn't expect any special treatment. Only her dogs get that. While prices start at 40 pounds for a simple trim, other treatments are extra and Mariah's dogs really seem to enjoy their wraps and full body massages," a source said.
"She pays for her doggies to travel with her first class on a whim. And when they can't she will check them into doggy day care at salons Chateau Marmutt. She also employs a designated chauffeur to ferry them to and from at around 400 pounds a time," the source added.
