Welsh Britain's Got Talent hopefuls Maia Gough, Groove Thing and Côr Glanaethwy set for live semi-final shows

Tonight sees the live semi-finals kick off on Britain's Got Talent - and three acts from Wales will be among those battling it out this week.

The semis will be on ITV every night this week as the contestants compete for a place in the grand final at the weekend.

Judges Simon Cowell, David Walliams, Alesha Dixon and Amanda Holden have whittled down all of the entries to just 45.

Bangor 160-piece choir Côr Glanaethwy are up against eight other acts in tonight's show.

Their initial performance of 'Benedictus' was described by David Walliams as "like being welcomed into heaven", while Simon Cowell said he "might be looking at this year's winners".

Twelve-year-old Maia Gough from Skewen received a standing ovation for her rendition of Whitney Houston's 'I Have Nothing' - described by Amanda Holden as "mind-blowingly fantastic".

But Maia says she'll be doing "something a little bit different" for the Britain's Got Talent semi-finals.

Appearing on Lorraine this morning, the schoolgirl spoke about her audition, saying: "It was all really surreal to be honest. I was really nervous before I went on, but when I started singing the fear goes away and it's really overwhelming and amazing."

Meanwhile young Port Talbot dance group Groove Thing travelled to London on Friday to start rehearsals for their live semi-final appearance on Tuesday.

A spokesperson for the group said: "They are extremely excited as their first studio rehearsal went amazingly well. They've got plenty of surprises in store for the audience."

The Britain's Got Talent live semi-finals begin tonight at 7.30pm on ITV.
