Singer Kimberley Walsh worried about her weighty issues

London: Singer Kimberley Walsh is worried about staying in shape once she finishes her stint in ‘Shrek: The Musical’.

The singer who took over the role of Princess Fiona last October is concerned that when her time in London`s West End comes to an end in May she will pile on the pounds because she won`t be so active. "Being on stage is a great way of staying in shape. We do eight shows a week and my dressing room is up two flights of stairs, so I`m always working out," she told Closer magazine in an interview. "I`m a bit worried about eating the same amount of food when I`m no longer doing the show. It`s been such a treat not worrying about what I eat," she said. Weight gain is not the only worry for the 30-year-old. She admitted her last night in the musical will be an emotional experience, reports contactmusic.com. "I`m worried about how I`ll get through my last night. It`s going to be so emotional. But it`s the right time for me to go. I won`t be doing more theatre any time soon. I need a holiday," she added.
