Interesting facts: Louis Walsh said Sharon Osbourne is “going to protect me” as he became the second contestant to enter the Celebrity Big Brother house. The former X Factor judge spoke about what he would be like as a housemate and told presenters AJ Odudu and Will Best: “I’m just going to be honest, I’m just going to be me, I can’t be anybody else.”

Upon entering the house, Big Brother asked Walsh if it was nice to be reunited with former X Factor panellist Osbourne. He said: “Absolutely, absolutely delighted to see her, we’ve loads to catch up on.” Speaking ahead of entering the house, Louis admitted "I'm not getting any younger" as he explained his reasons for doing the show.

"I don't cook, like at all," Louis confessed. "I can only just make a cup of tea and even then I use the microwave." In addition to revealing his worst potential housemate would be Donald Trump - "loud and in your face" - Louis mused: "I just want to have fun and meet some nice people."
