She’s the gorgeous Australian model who has reportedly caught Scott Disick’s attention.

And on Tuesday, Megan Blake Irwin proved her modelling credentials as she took part in an active photoshoot at Sydney’s Barangaroo area.

Although the shoot was for a fitness campaign, the pretty blonde was caught puffing on an unhealthy cigarette during quick breaks under the balmy sunshine.

The 21-year-old flaunted her toned abs and trim frame in all its glory, dressed in navy Running Bare leggings and a purple patterned crop top.

Her sporty getup was styled further with a white hoodie, bright pink gloves and a matching bralet, while she strolled along the pathways in white-soled trainers.

With her glossy blonde tresses swept away from her striking complexion, Megan perfected her smouldering pout as she showed off her athletic aesthetic during the day’s proceedings.

 In January this year, the stunner was 'discovered' by the world's most iconic photographer Mario Testino, who shot her for the April issue of Vogue Australia.

She and reality TV star Scott had most recently been seen putting on an affectionate display when they went for a dinner date at Koi Japanese restaurant in LA.

Neither have confirmed they are dating, and Megan on Wednesday refused to talk about their relationship – saying only he was a ‘lovely guy’.

Following a trip to Cannes, Scott was seen partying in London on Friday, after a dinner with Kim Kardashian West and Kanye West.

While in Sydney, Megan attended the launch of P.Jamé - a new sleepwear label run by model Bambi Northwood-Blyth and her husband Dan Single - and refused to confirm whether she and Scott were dating.

The beauty told The Daily Telegraph: 'Scott is a lovely guy but that's about all I'm going to say about that.'
