A star-studded sunset yacht party set sail from Melbourne‘s Docklands on Thursday night, with a host of Married At First Sight favourites stepping out in style for a four-hour cruise.

But it was groom Scott McCristal, 33, who stole the spotlight, appearing in high spirits as he partied alongside a mystery blonde.

The reality star looked relaxed and confident as he mingled with guests on the luxury vessel once owned by late INXS singer Michael Hutchence.

At one point, Scott was seen getting particularly close to the unidentified woman as the group enjoyed drinks and music against a glittering city backdrop.

Sources on board said Scott appeared ‘very friendly’ with the blonde throughout the evening, sparking intrigue among fellow guests.

The 110-foot vessel dubbed The Queen Royal is believed to be the first and only rose gold chrome superyacht in the world and has recently undergone a $1.5million facelift, according to current owner Matthew Sannen.

Spanning four levels, the floating party palace provided the perfect setting for the reality TV crowd to let their hair down.

Scott was later seen posing for photos with fellow groom Danny Hewitt, with the pair looking in great spirits as they wrapped their arms around each other for a friendly snap.

The group appeared to be making the most of the exclusive event, with champagne flowing and laughter echoing across the deck as the yacht cruised along the water at sunset.

Elsewhere, Scott was pictured alongside groom David Momoh and other guests, with the trio seen sitting together and soaking up the lively atmosphere as the city lights twinkled in the background.

Also on board were this year’s stars Chris Nield, Rachel Gilmore, Julia Vogl, Steven Danyluk and other reality TV personalities, including faces from Big Brother and Love Island.

At one point, eyebrows were raised when it became clear that married couple Rachel and Steven were both in attendance – but did not interact with each other throughout the night.

The lavish outing comes amid major developments in Scott’s personal life with his TV wife Gia Fleur.

Gia has well and truly moved on from her TV husband – and she is no longer hiding it.

The reality star, 36, recently stepped out in Melbourne with her new boyfriend Alan Wallace, months after her explosive split from Scott.

The pair looked completely at ease during a cosy café date at Chadstone Shopping Centre, chatting over takeaway coffees as they sat side-by-side in a leafy venue.

Gia cut a stylish figure in a plush brown teddy jacket layered over a low-cut black top, paired with crisp white trousers, while Alan kept things casual in a pale yellow hoodie and black trousers.

At one point, Gia leaned in close as she spoke, with Alan appearing fully engaged – their chemistry clear to see.

‘I can’t keep pretending I’m with Scott,’ Gia previously admitted.

‘There’s only so long you can fake something before it starts to eat away at you.’

She added that her connection with Alan developed naturally after filming wrapped, describing it as a fresh start following a difficult end to her on-screen marriage.

‘I didn’t go into this looking for anything,’ she said.

‘But sometimes the right person comes along when you least expect it.’

While Gia embraces her new chapter, Scott appears to be doing the same – with Thursday night’s yacht party proving he’s firmly back on the social scene.
