Simon Cowell's son Eric caused chaos on Britain's Got Talent's spin-off More Talent tonight.
Tonight saw the first semi-final with comedian Lost Voice Guy and singers the D-Day Darlings the two acts making it through to the final.
Following the main show on More Talent, Stephen Mulhern joined the judges for a chat.
And Simon brought son Eric along too, who caused mayhem.
Laughing into the microphone, Eric took over the show.
"Did you like being in the theatre tonight?" Stephen asked Eric.
"No," Eric replied.
"You couldn't write it, it was a dream," Stephen reacted.
Simon said: "Go and sit down with mummy for a second."
Simon recently revealed he's planning for son Eric to takeover his TV empire.
Music mogul Simon says he can see Eric one day sitting behind the judges desk of Britain's Got Talent.
Speaking ahead of the new series, Simon said: "I look at things through his eyes now.
“I want to spend more time with him. I’m lucky because he likes the shows, so he comes down to them with me. I’m sort of training him up.”
In an interview with The Sun newspaper, Simon said he'd "love" for Eric to takeover on the show.
"Oh, a million per cent. I think about that all the time. I would love him to take over. He’s really confident," Simon explained. “When he comes down here he knows what everybody does. He likes being in the gallery. That will be my dream.”
