She's gained a legion of admirers after memorably making her Victoria's Secret debut in a minuscule bikini in 2012. 

And Barbara Palvin showed off the body that helped make her famous as she worked up a sweat while playing volleyball at the Sports Illustrated Summer Of Swim Fan Festival on Sunday.

The 22-year-old model oozed sex appeal as she flashed her ample bosom and tiny waist in a plunging bikini top while basking in the sun in New York's Coney Island.  

Barbara - who was recently unveiled as Sports Illustrated Swimsuit Rookie Of The Year - arrived earlier on in the day with her new SI pals, Hannah Davis and Nina Agdal. 

And while she looked incredibly in shape, the beauty was forced to defend criticism over her weight after the first images of her shoot with Sports Illustrated were revealed earlier this year.
