Katy Perry breaks silence amid Justin Trudeau 'romance'

Love is in the air… or maybe just Katy Perry.

Hot on the heels of swirling romance rumours with Justin Trudeau, the Roar singer has seemingly broken her silence.

Two days after the former Canadian Prime Minister and Katy, 40, were reportedly seen dining together in Montreal, she took to Instagram on Wednesday to share a carousel of new concert photos with a two-word caption.

Attached with a Canadian flag emoji, the text read, "so far!"

The post featured stunning highlights from her ongoing Lifetimes Tour, which spans 84 shows across the globe.

The 15-slide post featured the Dark Horse songstress flying high above the crowd with the help of an invisible wire, a video of her proudly showing off a butterfly mic, a collage of pictures and several iconic on-stage moments.

Moreover, adding fuel to the already buzzing rumour mill, Justin was spotted in the audience at 13-time Grammy nominated singer's sold-out concert at Montreal’s Bell Centre on July 30.

The 53-year-old was seen in a casual black t-shirt, smiling from the crowd in a photo shared online.

His appearance came after a communications consultant for the restaurant Le Violon, where the two were seen on an alleged "date", confirmed that Justin and Katy spent about two hours at the fine-dining spot on Monday evening.
