Stavros Flatley star Lagi Demetriou is all grown up and is set to become a father.

The 25-year-old former dancer - who found fame with his 53-year-old dad Demi on Britain’s Got Talent back in 2009 - has shared a sweet video on TikTok announcing that his fiancee Annika Crawford is expecting their first child.

Demetriou captioned the video, which shows him kissing her baby bump: "To another new chapter with my beautiful wife to be. I love you @neekzs."

The couple have been together for five years and became engaged on New Year's Eve 2020.

Demetriou and his father took part in ITV talent show BGT in 2009 as a dance duo combining Cypriot and Irish dancing. They finished fourth in the third series, the same year as Diversity and Susan Boyle competed on the show.

In 2019 Stavros Flatley took part in Britain’s Got Talent: The Champions, competing against BGT favourites such as singers Collabro, Connie Talbot and Paul Potts, stand-up comedian Lee Ridley AKA Lost Voice Guy, sword-swallower Alexandr Magala, dog act and season four runners-up, dancing duo Twist and Pulse.

At the end of the show Lagi announced he was quitting the dance act.

He said: "We’ve done this for 10 years for a joke.

“We’ve done so many amazing things but what is there left to do? We’ve done the Royal Variety, we’ve played in China, Monaco - everywhere. So when we got to The Champions, I thought this was the right time to leave.”
