The special guests for the BGT live shows have been revealed.

The King of Latin music Ricky Martin will take to the stage on Monday 25 May to perform his new single 'Mr Put It Down'

Last year's finalists Jack Pack will take to the stage to perform a track from their new album on Tuesday 26 May

Britain's Got Talent judge Alesha Dixon will swap the judging panel for the stage on Wednesday 27 May to perform the world exclusive of her comeback single 'The Way We Are'

The new X Factor UK host Olly Murs will perform his new single Beautiful To Me in a world exclusive on Thursday 28 May

Last years winner Collabro will return to the stage for the first time since winning the show last year for Friday 29 May

Why is it just singers performing? Britain's Got Talent is supposed to be a variety show. If I was them I'd have:

Monday Semi Final 1- Diversity
Tuesday Semi Final 2- Attraction
Wednesday Semi Final 3- Ashleigh & Pudsey
Thursday Semi Final 4- Darcy Oake
Friday Semi Final 5- Collabro

erm Is that right Ricky Martin come back and singing I loved him

I can't wait to see new member of Jack Pack

Little Mix are rumoured for the final

Again, why?

It'll be ridiculous if the finale doesn't have at least one guest variety act.

SO are Fifth Harmony too!

Hope Adam Lambert coming on.

Zzzzzzzzzz at that line up. Obviously Olly Murs sticking his fat face in again. Wouldn't be a show without punch.

Singing acts sell records, variety acts don't

When is the final this year?

There's X Factor for that.

Get Kelly Clarkson for the final tbh

Fifth Harmony I think will be on the final. Just checked their schedule and it all adds up. They're playing GAY at midnight on May 30th, so they'll be in London.

What was Ricky Martin like..yay or nay ?

Kind of in the middle between 'yay' and 'nay'. So 'nyay'.
