Kelly Ripa appears to be wasting away and could face severe medical problems, The National Enquirer can reveal.

Our shocking beach photos show the pin-thin star of Live With Regis And Kelly escaping the winter blues on a Caribbean vacation.

The 35-year-old TV host’s bikini exposes a scarily bony chest that stunned passers-by on the island of Nevis, as she relaxed with husband Mark Consuelos and their three children, Michael, eight, Lola, four, and two-year-old Joaquin.

An eyewitness told The National Enquirer: “You had to feel sorry for her when you saw the bones in her chest. It made you wonder if anything is wrong with her.”

Kelly has repeatedly denied being a fitness fanatic and has always said she believes looking after her kids is enough of a workout.

But after examining our exclusive photos, medical experts said they feared the 5ft 4in star could be over-exercising — and could end up crippled with the bone-wasting disease osteoporosis.

Nutrition expert Dr. Sally Rockwell, who has not advised Kelly before, said she would like to see her take up a new food regime.

“I think her body is eventually going to collapse,” said the author of Calcium Rich And Dairy Free. “I fear she could leave herself susceptible to osteoporosis in later life because of what she is doing now.

“Because she has lost so much body fat I believe she is going to suffer from hormone imbalance, especially estrogen. She probably needs to have protein drinks containing flax oil and primrose oil.”
