Siannise Fudge and Luke Trotman very narrowly missed out to Paige Turley and Finn Tapp.
Winners Finn and Paige were pictured arriving at Heathrow from South Africa along with the other finalists.
The couple shared the £50,000 prize in Sunday’s live final.
The singer's ex-girlfriend Paige Turley is currently one of the contestants on the ITV2 reality show.
Paige Turley was unimpressed when it seemed Finn's head had been turned in Casa Amor.
The singer used a derogatory term used to describe a gay man in relation to her brother.
And he wants a cut of that prize money if she wins.
The 22-year-old West Lothian singer dated the music star when they were teenagers, and the pair have remained close.
I just can't believe we are already on week four of BGT. The time is flying faster than the 60 mile an hour blast-off on the Aerosmith rock'n roller coaster at Disneyland Paris (other great theme parks are available).
Our vox pops this week are people who are proud to be British.
