Last Saturday night saw all sorts of acts going before the judges from singers and dancers to a knife juggling, unicycling circus act.
Here we rank the Top 5 performances online after crunching those internet hits since Saturday's show.
Old Men Grooving
Patrick, Fred, Phil, David and Bret wowed the judges with their delightful dad dancing that turned into a full blown hip hop routine. The group, who only met up last year, have notched up an impressive 6 million views since Saturday night.
Cut from the main show, Forbidden Nights are a singing/dancing/stripping act all in one. The group's audition has proved to be quite the hit online although we can't imagine why...
12-year-old Welsh singer Maia Gough's performance of Whitney Houston's I Have Nothing was branded "mind-blowingly good" by the judges after the youngster belted out the diva hit.
20 year old singer from Bristol Aaron Marshall left Amanda Holden outraged with his bizarre cover of Frozen hit Let It Go. The other judges were won over and put Aaron through to the next round, if only to annoy Amanda.
Georgie 22, Katie 23, Rosie 22 and Enola 24 make up princess pop group Misstasia who brought a touch of Disney magic to the auditions at the weekend with their cover of Part Of Your World from the Little Mermaid.
