Louis Walsh has revealed his doctor believes he suffered a minor heart attack during Celebrity Big Brother.
Speaking on the 2 Johnnies podcast, the 74-year-old described the medical scare from his 2024 stint. The incident did not appear in the broadcast.
On the podcast, Louis has also ruled himself out of a rumoured X Factor reboot. He also opened up about his friendship with Sharon Osbourne, revealing she’s “not in a good place” following the death of her husband Ozzy last year.
Louis Walsh reveals ‘minor heart attack’ in Celebrity Big Brother house
In the episode, Louis said anxiety problems inside the CBB house led him to seek help from the programme’s medical team.
He recalled: “I thought it was going to be fun. It wasn’t fun. I had anxiety problems and I had to get the medics.”
Louis added: “My doctor thinks I had a minor heart attack in there.”
He also said he struggled to sleep while the house was dark and the contestants were locked in. At night, he sometimes tried to leave the enclosed set.
Staff let him out several times for tea, he said. He praised their care, but said entering the series had been a major mistake. Louis explained: “I did it for the money but I shouldn’t have.”
Louis also claimed Sharon Osbourne was not in a “good place” during her guest stint. The pair had previously worked together as judges on The X Factor.
