Paris Hilton -- Get a Cab!

Yes, she's really changed since serving jail time!

Miss Hilton was snapped by paparazzi -- getting home from a Wednesday night out on the town -- at 5:00 AM! Mornin' Sunshine!

Arriving in a taxi (she's learning!), the heirmess ditched her size 11 heels and shielded her exhausted makeup with a towel. Home at last!
