MasterChef Australia star Hayden Quinn has married his American model girlfriend Jax Raynor in Massachusetts.

The newlyweds tied the knot in a romantic beachside ceremony before celebrating with their friends and family.

Hayden, 36, looked dapper in a black tuxedo and bow tie while Jax stunned in a one-shoulder tulle gown.

The reality star shared a series of sweet photos from their special day to Instagram and simply captioned the post: 'Mr & Mrs Quinn.'

In one photo, the newlyweds shared a kiss after being pronounced as husband and wife.

In another, the couple couldn't wipe the smile off their faces as they walked down the aisle. 

Hayden announced his engagement to his American model girlfriend last December.

The couple shared their happy news on Christmas Eve, uploading a sweet photo of them posing with Champagne flutes in hand.

'Merry Christmas and Happy Engagement from us to all of you!!!' Hayden captioned the post. The couple began dating in 2016.

Hayden previously admitted that he wanted to propose earlier but the pandemic had made it 'tricky' to make their engagement plans official.

Jax relocated from Los Angeles to Sydney in the second year of their relationship to be with the MasterChef star.

Meanwhile, Hayden made such an impact during the 2011 MasterChef contest that the hunky star returned to the franchise for an all-star season in 2012.

He returned once more to the ratings blockbuster for the Back To Win season in 2020.

Hayden was a judge on Channel Nine's short-lived cooking competition Family Food Fight from 2017 to 2018. He also published two cookbooks.

His other credits include Hayden Quinn’s South Africa, a ten-part cooking series on SBS.

Hayden also fronted the ABC cooking series Surfing the Menu: The Next Generation, with Dan Churchill in 2016.
