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 fiancée Ramona Agruma enjoyed a well-deserved night off parental duties as they attended a Cannes Film Festival party on Tuesday evening.

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

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

Her flawless skin was glowing in a minimal makeup palette, and she wore her blonde locks out in beachy waves.

She flaunted 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 trousers.

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

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

The actress wowed in an elegant navy blue dress that featured intricate detailing around the waist and on the shoulders.

Ramona looked equally as glamorous in a lilac one shouldered gown teamed with silver heels.

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

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

The lovebirds were initially introduced to one another by a mutual friend in late 2021.

Rebel previously spoke to People and recalled how the couple had made an effort to establish a genuine connection prior to their first date.

The pair had already been dating for several months before the Australian actress announced the relationship and came out of the closet.

‘I thought I was searching for a Disney Prince… but maybe what I really needed all this time was a Disney Princess,’ Rebel wrote on social media at the time.

She announced the couple’s engagement in February, posting 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 future wife.

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

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

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

‘Happy Mother’s Day! (Just woke up at 5:30am and changed a big (poo emoji …how about you?)’
