The famed eight-year-old offspring interrupted his mother to say the celebrity couple split up as the cameras rolled in for an Instagram account on Tuesday.
Simon and Lauren cemented their status as a celebrity couple, dating for many years and raising their son Eric, six, together.
The celebrity couple are in California custody with their son and Lauren’s 14-year-old son Adam from a previous relationship.
Mom of two, Amanda, chatted with her 1.4 million fans to play her new NHS single for music mogul, 60, and catch up with longtime partner.
Things got in the way when Hollie asked when she thought Simon and Lauren had split up, seemingly oblivious to the live broadcast.
She said, “I thought they had broken up? “
Amanda replied, “Simon and Lauren? “
Hollie replied, “Yes. “
Amanda said, “Don’t be stupid. “
However, a spokesperson for Simon confirmed that the boss of X Factor and Lauren were “very good together”.
A spokesperson for Simon told The Mirror, “Simon and Lauren are still very close together and are locked out in California. “
Sources close to the couple also said that Amanda’s daughter had just been confused.
An insider told The Mirror, “It was just a case of a child being a child and he was confused and things went wrong. “
It comes after Amanda sprang up on Simon’s “kind invitation” to ask him to sing on Britain’s Got Talent live shows.
During the live stream, British judge Got Talent talked about his relationship with the music tycoon and his girlfriend Lauren.
“I played the album to Simon because Simon was very nice and he invited me to sing on Britain’s Got Talent live concerts, which I will do anyway.
“But I thought I’m going to take it and have a cup of tea and see what he thinks, I don’t know why I did this – it was one of the most trying things I have ever do in my my life. It was like the opening night of a West End show.
“I was sitting in his living room; I had nice homemade cookies from Geoff the chef. I don’t think they have a locked out chef.
“In fact, the lovely Lauren, Simon’s girlfriend, sent me some nice pictures of them cooking the other day. Simon is pretty good at cooking, I think. “
