Just four months after giving birth to her daughter, British model Liberty Ross is back on the scene looking more fabulous than ever. Leaving everyone amazed by her svelte figure, the supermodel attended the H&M's party, celebrating the launch of the company's new Knightbridge store, dressed in skinny blue jeans and a black vest.

The 26-year-old brunette claims there's no any special secret that helped her get back to her model measurements after the birth of Skyla Lily Lake.

"It's just in my genes," she told British Vogue apologetically. "My stomach was literally concave about a week after she was born. I haven't done anything to get back in shape."

Liberty Ross was discovered at the age of 13, but her true triumph came when she was photographed by legendary Mario Testino. In 2000, she was titled the Model of the Year at the Elle Style awards, and appeared on the anniversary issue of The Face. In 2003, she wed her long-term boyfriend, TV director Rupert Saunders.
