LONDON - Former Spice Girl Geri Halliwell, 34, has set tongues wagging over her lean new look.
Pals close to the singer, famous for her yoga worship and yo-yo dieting, say she's lost two-and-a-half stone and they are worried about her state of health.
According to British newspaperThe Sun, Geri is fretting about her weight and is determined to look her best for an appearance on a TV programme and a possible Spice Girls reunion tour.
Halliwell, 34, was snapped leaving an exclusive restaurant in London's Mayfair last week and onlookers described her as looking drawn in the face, with a non-existent tummy and knobbly knees.
Gone are the famous cleavage and hourglass figure.
A diner at the restaurant said: "I think she looks far better when she's curvy and sensuous. She looks in need of a good meal or two."
The singer, who has battled with eating disorders in the past, is said to have changed her body shape dramatically after giving birth to her daughter Bluebell Madonna in May of last year.
She was the picture of health then, thanks to a low-carb diet and strict fitness regime, but she's no longer in such great shape.
Geri was quoted as saying at the time: "I've gained weight but I feel healthy and sexier.
"I'm just over 5ft and my weight has ranged from six-and-a-half stone upwards, but I've never felt comfortable until now."
