Kimberly Stewart has fought with her famous dad Rod Stewart over her fitness regime.
The 35-year-old star - who designed a range of scarves for Rockins inspired by her 'You Wear it Well' singer father - revealed she is actually a gym fanatic who has had fights with her dad over the amount of time she spends working out.
She said: "I work out like a crazy person. My favourite workout is Tracy Anderson's. I do it in the gym with the heat on - 85 degrees Fahrenheit. You pour sweat and it's amazing. My dad thinks I'm crazy! He put a lock on the heat panel in the gym so I couldn't get into it. So I went and bought nine portable heaters, but they short-circuited the power. It was like gym wars."
Reality TV star Kimberly - who has three-year-old daughter Delilah with actor Benicio del Toro - revealed that she loves the gym so much that she can usually be spotted out in sports leggings, bras and hoodies.
She told HELLO! magazine: "Nowadays I have to be comfortable. I don't want to be running around in high heels with Delilah. I love vintage and dressing up is fun, but in the morning I through on my gym kit, brush my teeth then roll out the door."
