"Leona wanted to thank all her friends with a big blow out for her birthday. As soon as she arrived, her and her mates were treated mates were treated like princesses," a friend of Lewis said. “They dumped their bags, glammed up and headed for Pure nightclub where there was an entire VIP section just set up for Leona on the balcony. "The champagne and vodka kept coming. Leona started singing and dancing with her blonde pal, while her fans were waving at her. They were there to the end and I over heard them saying they wanted to take the party back to the hotel," the friend added.
