Kim Kardashian worried over `too big` derriere

Los Angeles: She is known for her curves, but socialite and reality TV star Kim Kardashian now wants to firm up her derriere. The 31-year-old Kardashian starts her day with a hardcore bootcamp class so that she comes into shape, reports dailymail.co.uk. Kardashian, who was at the gym early in the morning for a double workout, tweeted: "I think my butt looks too big in these jeans." Her backside looked too full in her black workout gear, which included a pair of lycra leggings. It was clear why Kardashian might be feeling a little concerned about her rear. But she is trying hard to tone up herself. "Early morning double workout. Bootcamp and pilates. Love starting my Monday like this," she tweeted. IANS
