Kate Moss is reportedly spending $1.6 million installing a gym in her new home.
The British model - who is famed for her wild partying - is determined to have a healthier lifestyle in 2011 and can't wait to use the fitness centre when she moves into the £8 million property in Highgate, north London next month.
A source said: "She's been talking to her architect and designer about how to use the gym space and is really excited about working out in there.
"Kate desperately wants balance in her life and she's one hundred per cent up for getting fit and healthy."
Kate, 37, is hoping to work out with her boyfriend, The Kills rocker Jamie Hince, with her new healthier outlook heavily influenced by close friend Sadie Frost.
The source added to the Daily Star newspaper: "Kate said she and Jamie will work out together when it's finally built, but in the meantime she has a brand new running machine in her present house in St John's Wood and a Swiss ball, which is keeping her busy.
"Kate's been heavily influenced by Sadie Frost, who's devoted to yoga and pilates after shunning alcohol for the past three years. Kate is in awe of her dedication. She now wants a super-toned body like Sadie's."
Kate - who has an eight-year-old daughter Lila Grace from a previous relationship with publisher Jefferson Hack - and Jamie are said to be moving from their current residence in north London's upmarket St. John's Wood as they feels it is "jinxed" after spending lots of money giving it a makeover when it was burgled, then later flooded.
