British singer Adele got some health tips from an unlikely source: Boy George! The 'Rumour Has It' singer has had to undergo emergency throat surgery in recent weeks to protect her vocal cords and to stem bleeding from a benign polyp. Boy George insisted that Adele should give up the habit, so she can enjoy a longer career as a singer. He told The Mirror: "If you're a singer and you smoke it really isn't a great idea. I gave up smoking six months ago which was the best thing I ever did. I used to try to convince myself it made me sound jazzier. It was very difficult to give up but I'm so glad I did." It was recently suggested that Adele will not perform any live dates until her throat is fully healed in the New Year.
