Nicky won't dis on her sis

Nicky Hilton remained tight-lipped when INF Daily caught up with her after a workout session in Los Angeles today. Smiling Nicky said ''I haven't seen her yet'' when we asked how newly freed Paris was enjoying her first hours out of the clink. And though Paris herself was lying low, she issued a statement saying: "I want to thank the Los Angeles County Sheriff's Department and staff of the Century Regional Detention Center for treating me fairly and professionally. I am going to serve the remaining 40 days of my sentence. I have learned a great deal from this ordeal and hope that others have learned from my mistakes.''
