British singer Sophie Ellis-Bextor is nursing a bruised foot after a dance performance went wrong. The Murder on the Dancefloor hitmaker is currently starring as a contestant on Britain's Strictly Come Dancing TV show and she narrowly escaped breaking a bone while rehearsing in front of her son, Sonny. The star, who is mother to three boys, took to Twitter.com to explain how she injured herself after slamming into her 17-month-old boy Ray's cot. She writes, "I thought I'd broken a bone in my foot demonstrating one of my dance moves to Sonny last night. I collided with Ray's cot... It's not broken, just bruised. I am an idiot though."
