Choosing her sibling over what seems to be her now-former BFF, Paris Hilton arrived at the brand new My House nightclub in Hollywood looking ever-so-glamorous on Friday night (January 23).
Accompanied by her sister Nicky, who was dressed quite the opposite in a simple grey t-shirt, black trousers and waistcoat, the hotel heiress sisters mingled with fellow clubgoers including Khloe Kardashian, Sean Stewart, Hanna Beth, Brittny Gastineau and Megan Good.
Meanwhile, as she gets used to life sans Paris, Brittany Flickinger was spotted out, as well, making her way over to a big birthday party at Eva Longoria's Beso restaurant.
Happily posing for paparazzi upon entrance, Miss Flickinger joined a guest list including Kristin Cavallari, Pauly Shore, Drew Carey and Playboy Playmate Nicole Narain.
Enjoy the pictures of Paris and Nicky Hilton partying at My House, along with shots of Brittany Flickinger out at Beso last night (January 23).
