Peter Andre desperate to gain weight

London: "Mysterious Girl" singer Peter Andre is currently spending most of his free time in the gym because he needs to be in the "best shape" ever for a forthcoming mystery venture. "I am working out like a demon at the moment because I`ve got a very exciting secret project coming up which means I need to be in the best shape of my life. I am working my backside off every day," femalefirst.co.uk quoted Andre as saying.

"I have got a personal trainer and I am aiming to put on a few kgs of lean muscle in a month," he added. Andre is finding the exercise part of his regime easy to follow, but he is finding it tough sticking to a strict diet. "It`s really tricky as I am not meant to be eating carbs at the moment, and as you all know, I love my pasta. It will be worth it in the end though," explained Andre. IANS
