Nicolette Sheridan Dayum, Nicolette!

She may be 45, but she's certainly showing the younger gen how to do it (I'll let you guys decide exactly what "it" is) at MyHouse Friday night, where the Desperate Housewife partied until 2am.

Ok, she does have a bit of the Madonna grandma hands thing going on, but in that dress, I'm certainly not looking at her hands.
