Martha Stewart is still not letting a little thing like house arrest cramp her style. The domestic diva was spotted by a Post reporter yesterday pampering herself at a tony Manhattan salon,in a weekend getaway that may have been a violation of her house-arrest rules. The femme felon visited Eva Scrivo in the West Village at about 12:30 p.m., apparently to get a facial and nail treatment.Gaping stylists and other clients looked on in shock.

It ‘s unclear if the denim-clad business queen ‘s visit was work-related,and therefore permissible by parole officers ‘ consent..It was also not know if she was wearing her mandatory electric anklet at the time. The sighting comes after the Aug.3 revelation that the 64-year-old domestic diva would be forced to extend her house arrest three more weeks in the wake of The Post ‘s exclusive report that she possibly breached her parole two other times.
