The ‘Mysterious Girl’ hitmaker is working hard to perfect his dance routines for ‘Strictly Come Dancing’ and wife Emily MacDonagh is adding more fatty foods to his diet in a bid to help him maintain a healthy weight.
A source said: ”Peter has been working around the clock and skipping meals. He has lost a lot of weight and Emily has been trying to fatten him up by putting extra calories in his food. She has been using extra butter and cream when cooking.
”Pete has also been getting advice from Thom Evans, who lost three stone when he competed. It’s a really tough show and can take its toll on the body.”
And the 42-year-old star – who is partnered with professional Janette Manrara, 31, on the show – sees The Wanted’s Jay McGuiness as his biggest competition.
The insider added to the Daily Mirror newspaper: ”Now Peter has Jay as competition, the pressure is on and he is determined to be in the final.”
Meanwhile, this week, Peter was joined by Emily at rehearsals for the BBC One show, with the doctor admitting his hectic schedule meant there was little time for the pair to spend time together.
She explained: ”I haven’t really seen him much this week; he’s been so busy training and working.
”It’s taken me by surprise how well he’s picked it up because It’s not easy, he’s shattered. The kids and me love to sit and watch him. I’m so proud and so impressed by how well he’s done.”
