Paris Hilton Red Christian Louboutin

Work it, girl!

Paris Hilton slipped into a sexy red dress and tights and grabbed a bite to eat in Beverly Hills on Monday, and after that the heiress headed to the Beauty by Tiffany spa.

P tweeted, "Just got an amazing facial at @90210BeautyRN. My skin is glowing, perfect place to go after a long flight. Loves it."
