Ryan Donnelly appears to be moving on in a spectacular way.

The controversial Married At First Sight groom was spotted getting extremely cosy with notorious socialite Suzan Mutesi at a raucous Studio 54-themed party over the weekend, just weeks after his split from TV bride Jacqui Burfoot.

The pair were snapped packing on the PDA in a dark booth at Pelicano in Sydney‘s Potts Point, leaving fellow party goers stunned as they passionately kissed in full view of the room.

Daily Mail Australia can reveal the steamy clinch went down during Suzan’s wild 39th birthday bash – and according to insiders, things between the two were ‘nothing short of X-rated’.

‘He was all over her,’ one guest revealed. ‘Everyone was whispering and watching – it was impossible to ignore.’

Mutesi, dubbed the ‘fake influencer’ after it was alleged that she inflated her follower count and Hollywood connections, appeared unbothered by the attention.

She dressed to impress in a barely-there silver sequin mini-dress with sheer cut-outs and dramatic shoulder detailing.

The social media sensation completed the look with platinum locks and glossy glam makeup.

Donnelly, 38, looked a tad dishevelled as he clung to the glamorous birthday girl.

His ex, Jacqui, has yet to comment on her former groom’s headline-grabbing night out.

The PDA spectacle stole the spotlight at an already star-studded night, which brought together a glittering (and chaotic) crowd of reality TV stars for the disco-themed bash.

Former MAFS brides Alyssa Barmonde and Olivia Frazer turned heads as they arrived together in glitzy mini-dresses.

The bash, hosted by Belvedere Vodka and Pelicano, transformed the venue into a retro party zone complete with disco balls, sequin frocks, and flowing champagne.

Also in attendance were MAFS grooms Tony Mojanovski and James Pappalardo.

FBOY Island’s Joey Robson, Love Island star Aidan Knox, and Beauty and the Geek’s Aaron Seeto with his girlfriend Caitlin Stewart, likewise came along.

Nineties ‘It Girl’ Tali Jatali made an entrance in a leopard-print bodysuit with a plunging neckline.

She paired it with a baby-blue micro mini and white knee-high boots, exuding Studio 54 excess.

Meanwhile, MAFS intruder brides Lauren Dunn and Veronica Cloherty were spotted mingling in the VIP section, staying clear of the Ryan-Suzan PDA storm.

Dean Wells also made an appearance alongside his fiancée Aimee Woolley.

The former reality star embraced the theme with a blush cardigan and white jeans, while Aimee shimmered in a teal velvet halter jumpsuit and gold accessories.
