Gorgeous Russian Eurovision star Polina Gagarina has been criticised as ‘worryingly thin’ by fans after posting beach snaps while on holiday in Turkey.

The pretty 34-year-old singer shared the photos on Instagram where she commands an army of 8.5 million followers.

The Russian stunner, who finished runner-up at the 2015 Eurovision Song Contest with the track ‘A Million Voices’, was holidaying on the Turkish Riviera when she posed for the beach snaps.

At the beginning of her career, Polina said she was overweight and embarked on a regime to shed the pounds, quickly turning herself into what she described as a “fairy”.

However, after hitting her ideal weight, she reportedly continued on the regime, and fans are concerned that she is appearing thinner all the time.

While wearing a hat and bikini on the beach, the photos, taken by her daughter, appear to show the singer with prominent ribs and skinny legs.

After posting the beach photos on Instagram, netizens said she appeared like a “skeleton” and claimed that she has lost far too much weight.

Instagram user ‘Katrina050516’ commented: “Polina, losing weight to the point of exhaustion is ugly.”

Netizen ‘Rise_to_dream’ wrote:” Someone needs to feed her something.”

‘Tanyakarpenko2903′ said: “Oh Polina, you are only one step from anorexic. It would not hurt to gain a couple of kilogrammes.”
