Britain’s Got Talent first semi-final line-up revealed in full as show goes live with eight acts tonight

BRITAIN's Got Talent has revealed its first semi-final line-up in full as the show goes live this week - with eight acts performing for a chance to win tonight.

Over the last six weeks the judges have picked finalists on Saturday and Sunday nights during the auditions that were filmed earlier this year.

The star-studded panel including judges Simon Cowell, Amanda Holden, Alesha Dixon and Bruno Tonioli selected the last few hopefuls in last night's episode.

Tonight, Ant McPartlin and Dec Donnelly will be back to introduce the line-up of stars who are vying for the huge BGT cash prize and the chance to perform in front of royalty at the Royal Variety performance.

Two acts from each semi-final this week will make it through to Sunday's grand final – with one decided from a public vote and the second decided by the judges.

Tonight's crop of semi-finalist are guitarist Sven Smith, 27, dog trainer Lucy Heath and her canine troupe The Trickstars, dancer Trey Braine, the Sslaubi Performance Troupe, cruise ship singer Taryn Charles, librarian turned rapper Bikoon, Ukrainian roller skaters Stardust, and opera singer Innocent Massuku.

The final of series 16 will also feature a special performance from the casts of Disney's The Lion King and Frozen, and a performance from judge Alesha Dixon who is marking her chart comeback after nine years.

Also on Sunday viewers will see the cast of Mamma Mia.

Judge Bruno has been known for his Golden Buzzer antics ever since he took on the role last year.

Last week the Italian was so keen to put dance troupe Phoenix Boys straight through to the semi-finals he broke the Golden Buzzer.

The 68-year-old displayed his passion as he accidentally broke the plastic buzzer.

Joining the boys on stage, the former Strictly judge became emotional as he explained why he sent them straight to the live shows.

A tearful Bruno said: "People don't understand how hard it is to succeed as a dancer.

"The work that goes into it and the passion and literally you do it for nothing, you do it for love and I felt that."
