The former X Factor judge famously championed Irish twins John and Edward Grimes back in the sixth series of the ITV show, putting them through to live shows.
But it seems he regrets that now.
When asked by Woman's Own what the most embarrassing moment of his career was, Louis replied: "Working with Jedward and putting them through on The X Factor! I'm definitely not in touch with them anymore."
Louis may regret working with Jedward, but we wonder if they really care that much?
After all, they have done pretty well since finishing sixth on the show, haven't they? Releasing three albums, modelling, doing panto, appearing in Celebrity Big Brother, landing their own CBBC TV series, befriending Hollywood actress Tara Reid and scoring a cameo in Sharknado 3: Oh Hell No!.
On top of that, they've worked with a string of charities, and represented Ireland at the Eurovision Song Contest twice – 2011 and 2012.
