Australian hurdler Michelle Jenneke's photos on social media at the Rio Olypmics have caused fans to speculate whether the athlete has gotten breast implants.
Jenneke, who rose to fame for her bubbly warmup dance at the 2012 World Junior Championships in Athletics Barcelona (video below), is preparing to compete in the 100-meter hurdles on Aug. 17.
While in Rio, the hurdler has been sharing photos on Instagram and fans have noticed something different about her body.
"Did you get a boob job?" one Instagram user commented on her photo.
"Surely she's had help there?" another user wrote.
Some are less convinced Jenneke had any enhancements, and rather that the differences can be simply be traced to a push-up bra.
"When guys don't know how sports bras or bras in general work lol," one of Jenneke's followers wrote.
Jenneke qualified for the 2016 Olympics after she won first place in the women's 100-meter hurdles in 12.93 seconds at the Australian National Championships in April.
