Justin Trudeau's mother Margaret Trudeau appeared to have a whale of a time as she joined his ex-wife Sophie Gregoire courtside for a basketball game on Tuesday evening.

Although the 77-year-old activist's son has moved on with popstar Katy Perry, family ties seem to remain strong as she put on an animated display next to her former daughter-in-law, 51.

Margaret and Sophie joined forces to support 18-year-old grandson and son, Xavier Trudeau, who took to the court for a halftime performance.

Together, they looked in high spirits as they watched the Ottawa Blackjacks and Calgary Surge match as they cheered from their seats. 

R&B singer Xavier launched his music career under the name Xav in February 2025 when he released his debut single, Til the Nights Done.

While dad Trudeau was absent for the performance and game, he did stop by during soundcheck the day before.

In a video shared on Xav's social media, Trudeau gushed that he was a 'proud dad.'

Trudeau, the former Canadian Prime Minister, was previously married to Gregoire for 18 years before they separated in 2023.

He shares three children with his ex-wife, which includes Xavier as well as daughter Ella-Grace, 17, and son Hadrien, 12.

Trudeau's new girlfriend Perry shares daughter Daisy, five, with her ex-fiancé, actor Orlando Bloom - who appears to have also moved on since their split.

Perry and Bloom ended their engagement and called it quits after nine years together in June of last year.

Following the breakup, Trudeau and Perry were first romantically linked in July 2025. 

Trudeau's son Xav has appeared to give his dad's new relationship his seal of approval.

In February, he described Perry as 'cool' and 'nice' in an interview with content creator G Hobs.

He also opened up about some of the topics they had bonded over, including their shared interest in music.

He said that he had 'talked for hours' with the 13-time Grammy nominee and had a conversation 'about [his] music' in particular.

'She gave me advice and next steps for me and stuff,' he added. 

Hobs asked if he and Perry ever talked about her trip and made a joke about 'going to the moon,' to which Xavier replied: 'We didn't talk about that. Did she even go to the moon?'

Last year, Xavier made another public appearance on The Brandon Gomez Show podcast and discussed his music career.

'I always loved music, whether it's creating it [or] listening to it. I always had a passion for it,' he said.

He also shared how his parents have encouraged him to pursue his passion.

'They've been supportive since the start,' he dished. 'Every single time I come back from the studio, I'd have something to show them, and we'd sit at dinner and just listen to it like, "Oh, I like this. I don't like that."'

He added: 'They love it. They're happy for me. They're happy I'm choosing my own path in life.'
