Sir Elton John and his partner David Furnish celebrated the superstar's 67th birthday on Friday (28Mar14) by hosting the grand opening of their new Las Vegas bar. The Rocket Man hitmaker and film producer Furnish were joined by actor Nicolas Cage, legendary producer Quincy Jones, rock matriarch Sharon Osbourne and her daughter Kelly, The Killers frontman Brandon Flowers, actress Britt Ekland and funnyman David Spade, among others for the launch of FIZZ Las Vegas. The Champagne lounge, a collaboration between Furnish and nightlife gurus Michael Greco and Steven Kennedy, is located next to Caesars Palace's famed Colosseum theatre, where Elton is currently performing a Sin City residency. Furnish tells USA Today, "Fizz is an extension of our personal style. Spending so much time in Las Vegas with Elton's performance schedule, we wanted a space that would reflect our personal style and become an extension of the way we entertain at home." And he tells U.S. breakfast show Today, "Once people are inside, it's very small and intimate... We bring the lights down to make it really, really chic and warm and welcoming. It's very much an extension of the way we would do things." Elton turned 67 on 25 March (14).
