In this evening's episode, auditions for the new series continued.
One of the latest acts to perform were Baba Yega.
They are an alien dance group made up of five mysterious dancers.
Following their unique dance to an original song, the judges were left rather unsettled.
Said Amanda Holden as the group creep around the stage in silence: "I find them really freakish."
Alesha Dixon declared: "They come with love! I love you guys, I think you're amazing. Unique, original different.
"Aliens have never won this show before and we welcome you to Britain's Got Talent," added Simon Cowell.
Giving the group a yes, he then quipped: "On earth when you get a yes, you have to kiss the people waiting on the side," prompting the aliens to chase Ant and Dec for a kiss.
"Joke's on them, I had garlic bread for lunch," says Ant.
Baba Yega made it through to the next round with four yeses.
As always, acts need three or more yeses to make it through to the next round and potentially on to the live shows.
Making up the judging panel this year once more are Simon Cowell, David Walliams, Alesha Dixon and Amanda Holden.
Meanwhile, hosts Ant and Dec will be present for the auditions, watching on from the sidelines with a comforting hug whatever the result.
There's also 16-year-old singer Amy Marie Borg from Malta who sings Nella Fantasia.
Britain's Got Talent 2018 auditions continue Saturday nights on ITV.
