Ant McPartlin returned to TV screens with a bang on Saturday night as he became emotional while listening to a Britain's Got Talent's act discuss he and his wife's IVF struggles.

In scenes filmed in January, before McPartlin stepped down from his presenting duties after being charged with drink driving, the TV presenter is seen tearing up at magician Mark Spelmann's story.

Londoner Spelmann wowed presenting duo Ant and Dec with his magic trick that involved a Rubik's cube, crayons and his wife's favourite book.

In a heartfelt moment, Spelmann said the real magic was the birth of his daughter, who was born through IVF, as he shocked the audience with the trick which involved a video of his child matching choices the judges had made.

Ant and Dec ran out from the side of the stage to press the golden buzzer, sending Spelmann straight through to the semi-finals.

"You got me in tears, man - remarkable," McPartlin told the contestant.

The TV duo were united on screen for the first time since McPartlin was charged with drink driving on March 22 following a road traffic collision on March 18. He is due to appear in court on April 16.

McPartlin is expected to be seen throughout the Britain's Got Talent auditions, which run to the end of May, but will be absent from the full week of live shows, which Declan Donnelly will present solo. Ant and Dec have fronted BGT since the show's inception in 2007.

Simon Cowell, Alesha Dixon, David Walliams and Amanda Holden returned as judges in Saturday night's episode, which saw an acrobat, an escapologist, a gospel choir and a dance troupe make it through to the next stage of the competition.

Britain's Got Talent fans welcomed seeing Ant back on screens, with many taking to Twitter to say they were glad to see Ant and Dec reunited.

Britain's Got Talent returns to TV3 and UTV next Saturday at 8pm.
