Although Dec impressed earlier in the week with a Greatest Showman-inspired opening sequence, the grand final included complicated choreography and a handstand aided by the Giang Brothers.
Have a watch of it below. It really is something special.
And fans on Twitter couldn’t get enough of it:
#BGT#BGTFinal 2018 If nothing else, this year has shown that #Dec can certainly hold a show together, entertain and present on he's own. Well played Sir. It's also shown that each judge still regard each of themselves more important than Anyone !
