Katy Perry and Justin Trudeaus Surprising Bond!

looked adoringly at her boyfriend in a loved-up snap shared to her social media as his son Xav praised their unlikely relationship.

The singer, 41, and the former Canadian Prime Minister, 54, cuddled up for the photo in matching black outfits, which was shared with a selection of others on Tuesday.

Alongside the cosy snap, Katy made a cryptic comment about 'karma', writing: 'Never knew karma could be so rewarding.' 

Smitten Katy looked delighted as she gazed at her boyfriend while lovingly resting her hand on his chest, as he smouldered to the camera.

The mother of one was wearing a chic strapless black dress with gold earrings, while her black hair was slicked back into a sleek bun.

Katy also posed for a couple of shots on her own, pulling a playful expression in one by sticking her tongue out. 

Katy also posted a sweet photo of her daughter Daisy Dove, five, who she shares with her ex-fiance Orlando Bloom, playing with rainbow lights.

The pop star also shared a photo of a fortune cookie message, that read: 'The stage is set. Soon you will encounter a whole new world of opportunity'.

Katy's series of snaps included a photo of herself as an older woman with grey curly hair, peeling prosthetic makeup off her face.

The selection of photo posted, including the cosy snap with Justin, comes after his son heaped praise on their romance.

Xav, 18, who is a budding musician, revealed that Katy is keen to help him professionally and he asks her for advice about songs he is working on.

Speaking on the Can't Be Censored podcast, he said: 'When I'm really happy with a song I send it to he. She's always happy to give me advice or tell me what I should change.'

He added: 'She's super nice. She's super down to earth. She's great. I think that my dad's happy so that's important.'

Xav said that he is 'used' to the noise that comes with his father dating a famous person after growing up in the public eye due his dad's role as a public figure.

He said that seeing a photo of them together, is 'just like any other picture of my dad and my mom. Or just my dad.'

His mother, Sophie Grégoire Trudeau, works as a public speaker, published author and mental health advocate. 

'My life is so crazy sometimes. I'm like, What is my life? What the hell?' Xav shared. 'I just laugh. The reality of it is, it's my life. What can I do? What can I change?'

Xav, who has received some heat for his attempts at releasing music, said he has learned not to care what other people think and write on social media.

He said: 'I've been told my whole life, "Don't read comments".

However despite his best efforts, he admitted it can get on top of him sometimes, saying: 'The hate, it gets to me sometimes.

'I guess it's built into my brain, I think of it as when someone comments on my video, when someone shares my video, when someone likes it, it just helps me.'
