Rebel Wilson shows off her weight loss in a sparkly green dress at Cannes with Ramona Agruma

They have their hands full with their daughter Royce after welcoming their little one via surrogate last year.

And Rebel Wilson, 43, and her fiancé Ramona Agruma enjoyed a well-deserved night off from parental duties when they attended a Cannes Film Festival party on Tuesday night.

The pair let their hair down during the Air Mail bash, held at the Hotel du Cap-Eden-Roc.

Rebel – who has impressively transformed her figure by losing 35 kg (77 pounds) over the past two years – looked sensational for the occasion in a sparkling green V-neck dress.

Her flawless skin glowed in a minimal makeup palette and she wore her blonde locks in sultry waves.

She showed off her most precious accessory – her Tiffany & Co. engagement ring – along with a large cocktail ring on her other hand.

Meanwhile, Ramona, 42, showed off her abs in a cropped Prada shirt with matching pants.

She pulled her own blonde locks back into a chic chignon and added a pop of color by applying a coat of red lipstick.

The two ladies have been at the festival for several days and were present at the Kerin Women in Motion Award on Sunday.

The actress sparkled in an elegant navy blue dress with intricate detailing around the waist and shoulders.

Ramona looked just as glamorous in a lilac one-shoulder dress paired with silver heels.

In some of the images, Rebel was spotted looking lovingly at her partner as the two women held hands and beamed at the cameras.

Rebel announced in June last year that it had started a romance with Ramona, owner of the sustainable clothing brand Lemon Ve Limon.

The lovebirds were first introduced to each other in late 2021 by a mutual friend.

Rebel previously spoke to People and recalled how the pair made an effort to form a real connection prior to their first date.

The couple had been dating for several months before the Australian actress announced the relationship and came out.

“I thought I was looking for a Disney prince… but maybe what I really needed all along was a Disney princess,” Rebel wrote on social media at the time.

She announced the couple’s engagement in February and posted photos to Instagram of the precious moment she proposed at Disneyland.

The sweet snaps showed her getting down on one knee with a Tiffany & Co. ring for her wife-to-be.

Months later, Rebel surprised fans when she announced the birth of her daughter Royce Lillian, born via surrogate.

The outing comes after Rebel and Ramona celebrated their first Mother’s Day and shared never-before-seen photos of their baby girl.

Despite being one of Hollywood’s most recognized actresses, the Aussie star let her followers know she’s just like everyone else and captioned the sweet photo of Royce in pink:

‘Happy mothersday! (Just woke up at 5:30am and turned a big (poo emoji…what about you?)”
