"The kids have taken over the show," said David Walliams, as 'Britain's Got Talent' sent two more finalists through to the weekend's final after an evening of entertainment on Tuesday.

Comedian Jack Carroll and singer-songwriter Gabz proved that the BGT audience can't get enough of this year's youthful contenders, more grist to Simon Cowell's mill following his stoush with Bruce Forsyth over recruiting underage contestants.

Jack Carroll was the first contestant to go through...

It was a kids-only final three in this semi-final with 14-year-old Gabz, Jack, also 14, and folksy duo Jack and Cormac, aged 13 and 14, vying for the weekend's two places.

After Jack Carroll went through first, David Walliams and Alesha both opted to go with Gabz, with Alesha saying she was voting for somebody she believed was "ready for the industry right now".

A reminder of Gabz's self-penned song during her audition...

In a bit of a contrast to the wholesome content on display in the competitive element of the show, was the guest entertainment in the form of a thigh-high booted Jennifer Lopez, complete with feathery stole and leotard.

"For anyone asking how you do it, that's how you do it," said Simon Cowell afterwards. "World class."
