Conor McGregor and Dee Devlin look the part as they rock up to Elvis premiere after party

The MMA star and 34-year-old Dee got close and cosy at the exclusive Cannes Film Festival event at Stephanie Beach as they sipped on cocktails and put their arms around each other.

Flashy Conor arrived suited and booted in a trendy blazer with rhinestone-adorned lapels and pockets, paired with slim-fit trousers while Dee took the plunge in a strapless Versace gown which featured golden buttons and safety pin-like detailing.

Dubliner Conor was snapped with singer Kylie Minogue at the glitzy event while Priscilla Presley, Winnie Harlow and Baz Luhrmann were just some of the big names who were also present.

The much-anticipated flick stars Austin and Tom Hanks, who plays Elvis’s infamous manager Colonel Tom Parker.

Director Baz Luhrmann, who brought the can-can to Cannes with Moulin Rouge! 20 years ago, chronicles the life and career of Elvis from his early days as a child growing up in Mississippi to his ascent as a rock and roll icon and movie star.

Luhrmann served as the film's director and co-screenwriter, along with Sam Bromell, Craig Pearce and Jeremy Donner, from a story he conceived with Donner.

Conor and Dee have been making the most of their time in Cannes this week.

The Notorious attended the prestigious annual Chopard Loves Cinema gala on Saturday, hosted by the luxury jewellery and watch manufacturer Chopard as part of the 75th annual event.

McGregor brought his fiancée Dee along to the event, which took place at the Hotel Martinez, and looked like royalty as they partied with a host of big names in the film industry, including Charlie Chaplin’s granddaughter Kiera Chaplin and model Adriana Lima.

The couple mixed and mingled with Chopard’s co-president, Caroline Scheufele, as well as her mother Karin, who seemed delighted to get up close and personal with the Irishman.

And McGregor even brought some of his Proper No. Twelve Irish Whiskey for guests to try, sharing a snap of him posing with a bottle of the alcohol in each hand on the red carpet.

On the night, Dee stunned in a white bodycon dress with blue patterned swirls while her beau donned a pale grey suit for the occasion.

The pair also arrived at the gala showing off their opulent timepieces, with McGregor opting for Chopard’s L.U.C Tourbillion in white gold.

The $630,000 (approximately €588,100) watch’s case and dial are completely set with “baguette-cut diamonds” which sit on top of an alligator strap.

Meanwhile, Dee’s wristwatch of choice is a white €19,310 Aquanaut Quartz from Patek Phillipe with 48 diamonds applied on the face.

Sharing some photos from the evening, UFC star McGregor said: “A truly proper night at ‘chopard loves cinema’ Absolutely Incredible!”

And mum-of-three Dee posted a few of her own highlights from the night, including some photos of her and Conor enjoying a refreshing sip of his whiskey.

“Amazing night with my man at ‘Chopard loves cinema’ gala dinner,” she said in an Instagram post.

“Proper Twelve in Cannes. so proud of you babe! I’m living for every second of this unreal journey we are on together.”

Commenting underneath her post, McGregor sung praises for his fiancée, writing: “Dee, you’re like silk gold on my arm, I am honoured and proud! I love you so much, the woman of my dreams."
