Katy subtly featured the former Canadian prime minister and "Roar" singer in her most recent Instagram post, though you'll miss it if you blink. The two have gone out together several times since this summer.
Katy posted a photo carousel from her celebrations in honor of her 41st birthday on October 25. These included a game of Monopoly Go with a side of wine, a celebratory birthday cake backstage at her Lifetimes Tour, and a night out in a seductive red dress with a high slit that she accessorized with black heels.
Additionally, Justin can be seen clapping and grinning in the background of the cake video, which shows Katy blowing out the candles before attempting to throw the cake at a crew member.
She wrote "Level 41" as the caption for the October 29 photo, along with a heart and lip-biting emoji.
Additionally, on October 25, Katy and Justin made their first public appearance together during her birthday celebrations, holding hands as they left a cabaret performance at the Crazy Horse Paris. According to pictures released by TMZ, Katy wore her red dress there, while Justin chose to wear a basic black suit and t-shirt by her side.
The couple caused more romance rumors when they were spotted cuddling on Katy's yacht weeks before their hand-holding adventure. In pictures released by The Daily Mail on October 11, Katy, dressed in a bathing suit, put her arms around a shirtless Justin and kissed him in one picture while Justin held Katy's backside in another.
Additionally, Katy, who has a 5-year-old daughter named Daisy Dove with her ex-fiancé Orlando Bloom, discreetly discussed her developing romance onstage during her Lifetime Tour just two days after the pictures went viral.
During her performance in the capital on October 13, she remarked, "London, England, you're like this on a Monday night after a whole day at work and a whole day at school." "It makes sense why I always fall in love with Englishmen."
"But not anymore," she joked.
Regarding Orlando's feelings regarding his ex's relationship with Justin, who is the father of Xavier Trudeau, 17; Ella-Grace Trudeau, 16; and Hadrien Trudeau, 11, with his ex-wife Sophie Grégoire Trudeau, the Pirates of the Caribbean star has previously made light of the matter.
After a satirical post suggested that Orlando—also father to 14-year-old son Flynn with ex-wife Miranda Kerr—had dined with former German Chancellor Angela Merkel, he responded with a series of applause emojis.
