After hosting a New Year’s Eve celebration (LAX nightclub) and partying all night long after that, the Hilton sisters still managed to get up on New Year’s Day for their next appearance. Paris Hilton and sister Nicky Hilton were on hand to help the opening of hair colorist Michael Boychuck’s new salon in Las Vegas’ Caesars Palace. The name of the establishment is simple yet effective: Color- A Salon by Michael Boychuck (he’s the one with blond highlights sandwiched between the sisters). So, will Paris Hilton get a free color treatment after helping promote the salon’s grand opening?? Hehe! Anyway, the hotel heiress was spotted posing in different parts of the salon with her trademark pouty, teasing look. The Hottie and The Nottie actress also signed a poster of her Rich Prosecco nude shot, an item many spectators wanted to get their hands on. Rich Prosecco is a “champagne in a can” product and Paris Hilton even went to Germany just for its ad shoot!
