It's semi-final week on Britain's Got Talent, and with a remarkable five Irish acts in contention, there is plenty for fans here to cheer for.

Flying the flag are 22-year-old Irish dancer David Geaney, singer Leah Barniville, and comedic dance duo Lords of Strut from Cork, along with two acts from Northern Ireland, St Patrick's Junior Choir and balloon artist Ryan Tracey.

On Tuesday's semi-final classical singer Barniville will be back fighting for her place in the final. The 14-year-old advanced after leaving the judges open-mouthed with her singing ability.

The Meath native stunned the judges with her rendition of Caruso by Lucio Dalla, and earned a standing ovation for her efforts.

Up the next day in the semi-finals is five time world champion Irish dancer David Geaney.  

The Dingle man wowed the judges with a stunning performance, backed by some impressive background visuals, landing himself in Wednesday's show.

Geaney, who works in his family pub in Kerry claimed afterward that "there's not much of n opportunity to put your talent on a big stage, and BGT is one of the biggest talent show sin the world".

He now has a big stage and an even bigger audience to showcase his impressive skills.

A fan favourite completes the set of Irish hopefuls as Cork comedic dance duo Lords of Strut will also take to the stage for the semi-finals.

Having recently performed on The Late Late Show (see below) and wowed audiences in the award-winning Dublin Fringe show, Riot,  'brothers' Famous Seamus and Sean-tastic (aka Cormac Kinsella and Cian Mohally) delivered a hugely energetic audition.

The duo's 80s themed routine to the sound of Aha's classic, Take On Me, saw them through to the semi-finals despite failing to impress Simon Cowell (there's a surprise!).

There's great anticipation as to what the lad's will pull out of the bag for their semi-final performance.

But anyone who has seen their performance during THISISPOPBABY's Riot show, including a cling-film wrapped Jesus being walloped with foam batons (trust us it's hilarious), will know that the judges and audiences are in for a treat.

Also through to the semi finals are St Patrick’s Junior Choir from Drumgreenagh in Co. Down.

The primary school group wowed the BGT panel during their original audition when they performed a rendition of Keane's Somewhere Only We Know and received a standing ovation from the audience.

The boys and girls will be performing tonight and school principal, Sorcha Lyness, says they "have worked really hard" in the run up to the show and added that "it's so nice to have them recognised in this way".

And last (but not least) is Omagh man Ryan Tracey who not only booked himself a place in the semi-finals but also smashed a Guinness World record for balloon modelling - while blindfolded - during his memorable appearance on the show.
