Jessica Simpson's is reportedly 10lbs lighter after turning to exercise following her split from Tony Romo.

Rather than moping around at home, the singer is channelling her heartbreak into workouts and healthy eating in a bid to get her old body back, say sources close to the curvaceous blonde.

“Right after Tony ended things, Jessica said, ‘I want my old body back,’” a friend tells OK!.

“She went into her kitchen, got a trash bag and started to clear it out.”
 
The source adds: “Jess is serious about getting her body back into fighting shape. Working out is helping to give her focus and clear her head. It’s better than sitting around moping or throwing pity parties with ice cream sundaes.”

Jessica is said to be determined to put those photos of her looking chunky than usual while on stage in January behind her once and for all.

“She doesn’t want to give anyone more reason to not take her seriously,” explains the pal. “She’s tired of weight being a talking point.”
