My, he's grown! Stavros Flatley's Lagi Demetriou is as tall (and big) as his father as they take to the Royal Variety Performance stage

They rose to fame and popularity as the tongue in cheek father and son act on Britain's Got Talent in 2009.
And it seems Stavros Flatley are still doing well for themselves as they shared the stage with the likes of Girls Aloud and Neil Diamond on Monday night for the 100th Royal Variety Performance.
But while it was a coup for Demi and Lagi Demetriou to perform in front of the Queen herself at the Royal Albert Hall, their act seems to have lost its cute novelty value as a result of Lagi growing as big as his father.
Spot the difference: Stavros Flatley have lost their novelty value as Demi's son Lagi inevitably grows up to be the same height and size as his dancing father
He's grown! Lagi was 14 when they auditioned on Britain's Got Talent, when he appeared as a mini-me of his father
Fans have been wowed by the pair over the years, in particular thanks to Lagi's mini-me type look next to his portly dad when he auditioned on the show at the age of 14.
But now the teenager has grown just as tall and big, making them appear like spitting images of each other.
Now appearing more like a dancing double duo rather than a father-son novelty act, the pair showed off their new look in front of the Queen on Monday evening.
