Australian hurdler Michelle Jenneke is setting hearts aflutter yet again - this time appearing in a racy bikini-clad photoshoot for Sports Illustrated.
The 19-year-old became an internet sensation last year after appearing in two viral videos performing what became known as her trademark hip wiggle dance.
The first video was shot as she warmed up for a 100-metre hurdle race at Barcelona's Junior Athletic World Championships in July and gained more than 19 million views on YouTube.
Quirky US website The Chive then featured Jenneke in a parody video in December.
Now Jenneke's posed for Sports Illustrated, chatting about her athletics career and appearing in bathroom, swimming pool and balcony shots in a range of bikinis.
"I like the challenge of hurdling - it's a bit more technical than straight sprinting," she said in a video published on the Sports Illustrated website.
"I feel it's what I was born to do."
Jenneke also performs her dance in the video, roping in the photographer and artistic director to have a boogie alongside her.
"I wouldn't even say I really came up with it," she said of the dance.
"It's just something that sort of happened in front of my races.
"Someone got a hold of the footage and decided to post it on YouTube and somehow it racked up a lot of hits."
She might be racking up a few more now.
