Simon Cowell, Amanda Holden, David Walliams and Alesha Dixon are all back on the judging panel of the ITV show.
Acts made famous from the UK version Britain’s Got Talent and its various international counterparts will battle it out to see who is the cream of the crop.
The Nelson Twins, Chris and Justin Nelson, will be in this evening’s episode taking a cheeky swipe at the Royal Family.
The pair reached the Australia’s Got Talent final back in 2012 and will be trying to make the UK judges laugh tonight.
Prince Harry and Prince William are in the firing line as they joke about the brothers “sponging” off of the Queen.
They say: “We actually love the royal family.
“We haven’t got jobs and we’re sponging off our gran, we’re very like William and Harry.”
Prince Philip is also the target of a joke following the car crash he suffered earlier in the year.
The twins jest that they share a driving license after one of them flipped their car, calling it “the Prince Philip”.
Many of the competitors will be familiar to UK viewers from years gone by.
One such act is singer Connie Talbot, who originally appeared on the programme when she was just six years old giving a rendition of Somewhere Over the Rainbow.
Now 18 years of age, Connie is back to sing her own song and the judges are shocked by her transformation.
Simon remarks: “Connie, you have teeth!”
He adds: “I will remember that first audition for the rest of my life. I don’t think we’d be sitting here now if it wasn’t for you.”
Connie made it to the final back in 2007 but lost out on a win to Paul Potts who also stars on the Champions show.
Meanwhile, Amanda’s set to get a fright from Asia’s Got Talent act The Sacred Riana.
Viewers will see her present a book to Amanda before asking her to name the final male victim of murderer John Hill.
She’s also instructed to rip out a random page then Riana goes on to drag her to the stage.
“Oh god, oh god,” Amanda says as Simon declares: “This is the scariest act we’ve ever had.”
Britain’s Got Talent: The Champions launches tonight at 8pm on ITV.
