In a video posted to his Instagram story the pair could be seen screaming and jumping up and down following the dive.

"I did say they would hear us from Canada!" Black wrote.

He also shared a message to Twitter to congratulate Daley, 27, and Lee, 23.

"No words! So so many tears! @TomDaley1994 you're an OLYMPIC CHAMPION! Congratulations Tom and @MattyLee !" he wrote.

The couple celebrated their fourth wedding anniversary this year after tying the knot back in 2017.

They welcomed son Robert 'Robbie' Ray Black-Daley the following year in June 2018 via a surrogate. He is named after Daley's father Robert who died from a brain tumour in 2011.

He said: "Hello Lance, Robbie and Mum, because you'll all be together by now, I just wanted to say a massive thank you for everything you have done for me up until this point.

"As you know, the support from you guys has been able to get me through some of my crazy days, some of my easy days, the highs, the lows and everything in-between.

"I think this journey from Rio where I was at my lowest point in my sporting career to now coming into this Olympics in a completely different mind space, I'm excited. And the fact that you guys make me feel loved regardless of how I'm going to do makes things a lot easier, it takes a lot of pressure off of me.

"So thank you for that and I miss you guys a lot, I can't wait to see you. I love you."
