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 Cannes Film Festival.
McGregor brought his fiancée Dee Devlin 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”
