Jackson aids Roberts' slimming efforts

Oscar-winning actress Julia Roberts is quickly shedding the weight she gained during her pregnancy - thanks to pop superstar Michael Jackson.

The Erin Brockovich star and her husband Danny Moder welcomed their twins Hazel Patricia and Phinnaeus Walter into the world in November and the actress has since been working hard at shedding the excess pounds she gained.

Pals say the screen beauty has been supplementing her health and fitness regime by dancing away to Michael Jackson: The Ultimate Collection to help her get back in shape.

A source says: "Julia is not one to sit around and do nothing."
