Kathy Hilton’s top birthday gift? A day at Michael Boychuck’s COLOR Salon at Caesars Palace in Las Vegas. Kathy enjoyed a soothing Chardonnay manicure and pedicure, normally priced at $100 and $145, and airbrush makeup in preparation for a night out on the Strip on March 14. The socialite celebrated her birthday with her husband, Rick, and close friend Faye Resnick with dinner at Simon at Palms Place, where Chef Kerry Simon presented her with a vanilla cake with strawberry filling. The group later enjoyed the nightlife at Encore’s XS.
