Susan Boyle has won her place in the Britain's Got Talent final

Britain's Got Talent star Susan Boyle is through to the final.

In tonight's show, the 48-year-old performed Memory from the musical Cats and received the most viewers' votes.

Susan was so delighted, she did a little dance on stage and called Piers Morgan 'Piersy-baby'.

The cheeky Scot also wandered away from the cameras and had to be brought back by Ant & Dec.

'I really enjoyed myself, I enjoyed every second,' she beamed. 'Pressure? What pressure?'

The YouTube clip of Susan singing I Dreamed A Dream from Les Miserables for her BGT audition is on course to be the site's most-watched video ever.

Also in the Britain's Got Talent final are dance troup Diversity who Piers and Simon Cowell put through ahead of 10-year-old Natalie Okri in the judges' vote.
