Justin Timberlake stopped his show so a man could propose to his girlfriend

Speaking from the stage, he said: "I see a sign that says, 'May I propose to Sarah?' You ready? You got it!"

The audience member, who turned out to be called Donald, composed himself as the crowd cheered and he got down on one knee.

He said: "I love you, you're my best friend. Will you marry me?"

The moment was beamed around the arena via the screens normally reserved for the main act and the audience cheered once again when Sarah accepted Donald's proposal.

Donald placed the engagement ring on Sarah's finger and the 'Cry Me A River' hitmaker congratulaed them before going back to his setlist.

He said: "Make some noise for Donald and Sarah! I can't top that. Alright, thank you. Have a good night everyone."

Just three days days before that romantic moment, Justin - who has been married to '7th Heaven' actress Jessica Biel since 2012 and has Silas, nine, and Phineas, four, with her - Justin was performing in Montreal, Canada on his wedding anniversary, and made sure to pay tribute to his wife, who was in the audience.

He said: "My wife is here tonight. And tonight is our 12-year anniversary. So, be nice to her, Montreal, because she's sharing me with all of you guys tonight. I love you, baby.."

Jessica previously noted that finding a balance between family life and work life was a "work in progress" for everyone when Justin was on the road and they had to rely on Zoom and Facetime to keep in touch.

Speaking on ABC's 'The View', she explained: "It's always a work in progress, right? It's constantly trying to find the balance, trying to find the time we can connect. Thank goodness for Zoom and Facetime. For parents who are gone a lot, that has been really helpful. Just finding the time we can connect and see each other in person or get him with the kids.

"We've never done this before with two, I'm exhausted. There's been four shows. I don't know how he's gonna do it or how we're gonna do it but we're gonna get through it, somehow, some way!"
