ITV has launched its latest "celebrity learning new tricks" show, Popstar to Operastar, which sees eight singers more accustomed to pop music train to sing opera. Myleene Klass and Alan Titchmarsh host, with Meat Loaf, Laurence Llewelyn-Bowen, Rolando Vincenzo and Katherine Jenkins mentoring and judging Myleene's old Hear'Say pal Kym Marsh, McFly's Danny Jones, Blur's Alex James, Pop Idol's Darius Campbell, Nolan sister Bernie, The Saturdays' Vanessa White, Shakespeare's Sister Marcella Detroit and Osmond family member Jimmy. To get an idea of the show check out PopSugarUK reader ellievolia’s experience of the dress rehearsal on her OnSugar blog. We've seen celebrities learn to dance, ice skate, conduct and perform in a circus, and it's intriguing when a new idea is put into practice. I'd love to know what you think, so vote to tell me: is it a great concept or a step too far?
