Hard to believe Tara Reid is only 37?

The former host of E's reality show Taradise hit the streets of London after partying with a mystery male companion at LouLou's in Mayfair.

Reid showed off her skinny stems in a glitzy mini dress and peep toe Louboutins.

Tara has taken so many lickins' over the years ... but she keeps on tickin'!
