Paige Spiranac stole the show on Saturday when she arrived at the Flemington Racecourse in a stunning white dress.

The former professional golfer, 29, flaunted her incredible figure in a form-fitting strapless gown which dropped to mid-calf in a mermaid cut. 

Red floral designs stood out beautifully against the white frock and matched her bold red lip perfectly as she posed at the Melbourne Racing.

She slipped into a pair of sky-high white strappy heels and completed the look with a white tulle fascinator.

Spiranac then curled her golden locks and piled them all over one shoulder for a sophisticated look. 

The beauty also posed alongside Bruce McAvaney, who she was excited to meet and quipped that the television presenter 'is looking special'.  

It comes after the glamorous model and social media personality was a surprise guest at Manly Sea Eagles training on Wednesday.

Before she donned a Manly jersey to play footy on Brookvale Oval, Spiranac teamed up with hulking prop Toafofoa Sipley to take on Reuben Garrick and Jake Trbojevic in a nine-hole game at the picturesque Bayview Golf Club in Mona Vale, on Sydney's Northern Beaches.

Despite sinking a roughly eight-foot putt described as 'clutch' by Garrick, and striking some sweetly-timed drives, Spiranac and Sipley went down by one stroke - but it only got the American even more fired up.

They then returned to the club's home ground, Brookvale Oval, where Spiranac showed she was far from a one-trick pony.

The athletic former golf pro, who has been featured in Sports Illustrated's Swimsuit edition and was named 'Sexiest Woman Alive' in Maxim's Hot 100 list last year, took to tackling with aplomb.

She sent the tackle bag flying with all the grace and determination of a footy player, remarking: 'If you give me something to tackle just know I'm going all out, lol', on a photo of her tackling it so hard she was about to faceplant on the 'Brookie' turf.

To prove it was no fluke, Spiranac then banged home a goalkick from right in front, jumping up and down in delight as it sailed over the cross bar.
