Anastacia is dating a new mystery man. The 47-year-old singer is currently in the UK rehearsing for her upcoming tour but is having the most fun in the evenings when she can go on dates. Discussing a typical day, she said: "I'll eat dinner after the show and have fish, veg and mash. "The evenings are fun because I am dating. I don't want to be specific but I am enjoying it." The 'I'm Outta Love' singer is currently struggling to sleep because her body clock is out of sync. She said: "My body is confused at the moment and wants me to go to bed at 4am. I always have less sleep before I start touring, but life is wonderful." Anastacia is currently preparing her costumes for the stage show and admits they have changed now she is getting older. She explained to Britain's Closer magazine: "I'm in the process of sorting outfits. I'll probably have four changes on this tour and I have a storyboard in my head of the looks I'd love. I'm 47 and there's a little more Lycra involved these days!
