Ant McPartlin and Declan Donnelly opened the first Britain’s Got Talent live semi-final by announcing that Alesha Dixon is having a baby.
The presenters revealed the judge’s news by singing a song which included the line: “And Alesha is expecting!”
After they spilled the beans, a thrilled looking Dixon said she was “very happy”, as her fellow judge David Walliams joked that the baby was really his.
Dixon, 40, has a five-year-old daughter, Azura, with her partner Azuka Ononye.
She has previously said she would like to expand her family.
The Britain’s Got Talent semi-finals continue on Tuesday.
The winner of the ITV series will win a cash prize and the chance to perform at the Royal Variety Performance.
