Cowell and his girlfriend Lauren Silverman, with whom he is expecting his first child, recently adopted two pooches and they are enjoying the lavish perks of his wealthy ways, including regular visits to a spa, reported Contactmusic.
"Simon takes the pups to a pet spa once a fortnight for doggy pedicures and massages and they even have a therapist who promises 'zen dog happiness'," a source said.
The pet pooches have their own bedroom, which is furnished with a king-sized bed and a specially-commissioned sofa.
"They're spoilt rotten! They sleep in a special king-sized bed on the very best cotton, eat and drink out of fine china bowls and follow a special organic diet. They drink bottled water and he treats them with T-bone steak once a week," the source added.
