The Firework singer has been spotted enjoying the sun with her British beau while in France for the Cannes Film Festival in recent days, but they have so far avoided posing together for the cameras at red carpet events like the amfAR Cinema Against AIDS Gala, which they both attended on Thursday night (19May16).

However, Katy and Orlando have since made their official photo debut in a funny snap the pop star posted to her page on Friday (20May16).

In the image, they wear matching white hotel bathrobes over their swimwear, as they lay sprawled out on the steps of the Hotel du Cap-Eden-Roc, where Katy had performed during the charity gala the night before.

She simply captioned the shot, "we cannes't (sic)," suggesting they were still recovering from the party.

The couple, which has been dating since January (16), has been keeping a low profile while in the south of France, but the stars were photographed looking affectionate on a yacht last weekend (15May16), and dining with actress Kate Hudson and supermodel Kate Moss earlier this week (begs16May16).

Their Cannes outing comes after Orlando was accused of cheating on Katy with Selena Gomez, after photos emerged of the pair hugging while partying together in Las Vegas following the Come and Get It hitmaker's gig in Sin City on 6 May (16).

Katy, 31, brushed off the drama on Twitter last week (12May16) by posting a link to an article Orlando had written for Time magazine about his work as a United Nations Children's Emergency Fund (UNICEF) ambassador. With the link, she warned her fans against paying attention to the "dumb conspiracy" adding the hashtag, "#dontfeedthebeast".

Selena, who has been friends with Orlando for years, echoed Katy's sentiments and showed solidarity by retweeting her message and adding a raised hands emoji. In a separate tweet, she referenced her song Kill Em With Kindness and wrote, "one day they'll get it lol (laugh out loud)."

Meanwhile, Katy and Orlando, 39, are expected to jet off to Mexico, where the singer is said to be among the guests invited to attend actress Eva Longoria's wedding.

The Latin lovely will exchange vows with TV mogul Jose 'Pepe' Baston at the Acapulco home of Jane the Virgin star Jaime Camil on Saturday (21May16), according to
