All the auditions are over and, on Bank Holiday Monday, the live semi-finals begin and will run nightly.
So, who are the 40 acts that judges Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams put through to compete with the five Golden Buzzer acts?
Here they are:
VARIETY ACTS
The judges say that what they would love to put before the Queen is a variety act…
So how about nine-year-old Jesse Jane McParland (pictured), who flew about the stage with a sword in her martial arts performance?
Hula hoop performer Lisa Sampson was also something different in her audition. But how different can she be in the semis?
And will Peter Lambert be able to get on his uni cycle this time around?
DOG ACTS
Jules trains guide dogs - and her Border Collie Matisse. Their audition brought the judges and audience to their feet.
Mitch and Cally The Wonderdog want to break the Guinness World Record for popping the most balloons in a minute. Cally failed in the audition but has been given a second chance.
Controversial ventriloquist Marc Metral is back with his dog Wendy, who appears to speak due to a fake nose and tongue attached to her like a muzzle. Will that put viewers off voting?
MAGICIANS
Simon said he now “believes in magic” after Jamie Raven’s audition. Will he still believe after his semi-final performance?
Jeffrey Drayton was judged to be so bad he was good in his auction with puppet Chantel.
Austrian Michael Late’s audition was just good enough to get him. Will he get past the viewer vote?
How did Chloe Louise Crawford get from the BGT stage to a balcony? And what will she do in her semi-final performance?
IMPRESSIONISTS
Andrew Fleming is bitter that he hasn’t made it big so far. Having seen his audition, the judges have decided he deserves a shot at fame.
Judges also liked Danny Posthill’s impressions of David Beckham, Billy Connolly and Gary Barlow.
DANCERS
When Luca Calo strutted out in very high heels, he started off singing and Simon, Amanda and Alesha buzzed. Then he started busting some eye-popping moves… That’s what got him through to the live semis.
The judges could barely watch Bonetics, a dancer-contortionist, but we’ll be seeing him again.
Brother-and-sister roller-skating act Billy and Emily England skated through after making the judges gasp with their fearless dance routine.
Remember Old Men Grooving, the dancing dads? They’ll be dancing again, too.
The other oldies but goodies, burlesque dance group Ruby Red Performers, are also through. Will they be stripping off again?
Siberia’s UDI, who teach dance to disabled and orphaned children, will return with another neon show.
OK Worldwide, the free-running, breakdancing, four-man dance troupe, also made it through.
Jonathan Lutwyche, from Gibraltar, performed his own contemporary dance that Amanda thought was “beautiful and heartfelt”.
Tap-dancing Beat Brothers are also through. Will they dance topless to please David?
Seventeen-year-old Dylan Byrd left home in Ireland for the first time to audition and the judges have made it worth his while…so far.
The 12-piece dance group Groove Thing, aged seven to 11 years, were just “too cute”, said Amanda.
Twenty-six-piece dance troupe IMD Legion include dance duo Lauren and Terrell, who auditioned for BGT last year.
Plus Entity Allstars, Alesha’s Golden Buzzer act and Boyband, who are Ant and Dec’s Golden Buzzer act.
MUSICIANS
Simon Cowell likes family acts and he liked the Kanneh-Masons, two brothers and four sisters who performed classical music playing piano, violins and cellos.
Simon didn’t like Narinder Dhani’s comb-playing routine, but he’s in the semi-finals.
SINGING GROUPS
The Kingdom Tenors - there’s 12 of them! - raised the roof with their performance of Westlife’s You Raise Me Up
Possibly the cutest boy group of this year’s show, The Sakyi Five - all brothers - stumbled with their first song, but won over Simon with their next choice, 1D’s Little Things.
Also through is The Neales: Dad Laurie and his three sons, who are helping Dad live out his dream.
The Honeybuns were the very last act to audition, singing It’s Raining Men and being showered with praise.
Misstasia are a very different girl group, singing Disney’s Part Of Your World from The Little Mermaid.
The 160-piece choir Cor Glanaethwy from Wales packed out the stage and you could have heard a pin drop as they sang Hosanna In Excelsis.
“I felt like I was being welcomed in Heaven,” David told them.
Plus Revelation Avenue, Amanda’s Golden Buzzer act.
SOLO SINGERS
Teacher and mother of five Becky O’Brien, 34, sang Over The Rainbow as is over the moon to be in the semis.
Ella Shaw, 18, sang her own song Summertime at her audition and it got her into the semis.
Super nervous opera singer Emma Jones, 23, got a standing ovation at her audition after singing Ave Maria.
Eleven-year-old Gracie Wickens-Sweet, who Simon said was “cute and very controlled” after she sang Somewhere Over The Rainbow.
The also-cute Henry Gallager, 12, who sang his own song, Lightening, about a girl he has a crush on
Another 12-year-old, Maia Gough, who belted out Whitney Houston’s I Have Nothing
Isaac Waddington, who blew the judges away with his performance at the piano, singing Billy Joel’s Always A Woman
Alison Jiear, 50, who sang You’ll Never Walk Alone. Not quite unknown as she has received a nomination for a Laurence Olivier Award for Best Actress in a Musical for her role in Jerry Spring: The Opera
Plus Calum Scott, who was Simon’s Golden Buzzer act and Lorraine Bowen, who is David’s Golden Buzzer act.
Britain’s Got Talent Live Semi-Finals start on ITV, Monday, May 25, 7.30pm and run nightly.
