Strutting her stuff on the blood-red carpet, True Blood star Anna Paquin shocked crowds with her look – but for all the wrong reasons.

Wearing a David Kroma little black dress, the 30-year-old actress' body looked surprisingly skinny, displaying hollow cheeks, rail-thin legs and boney shoulders.

The blonde beauty gave birth to her and co-star/husband Stephen Moyer’s twins – Charlie and Poppy – less than a year ago. While the 5-foot-5 starlet has always been in shape, her newly debuted look appeared anything but healthy. Nutritional therapist Elena Michaels tells Life & Style, “She looks 20 pounds thinner. She’s dangerously thin.”

To bounce back to her gorgeous state, Michaels says the star “should eat more protein and veggies. She needs to gain at least 15 pounds.” The expert also recommended that she cut back on the length of her exercise routines.

“Many celebrities work feverishly to lose the baby weight – but she has to make sure she’s not overdoing her workouts,” Michaels explained.

Hopefully Anna will take up on the professional's advice and sink her fangs into a new, healthy lifestyle.
