Simon Cowell told Louis Walsh to sort out the bags under his eyes.

The 'X Factor' boss has just asked the music manager to reclaim his seat on the show's judging panel after he was dropped and replaced last year, but he recommended that he get his dark circles seen to prior to the programme returning to screens in October.
He explained: "I've never done botox in my whole life. Simon said to me I had bags under my eyes so I went to his doctor in Los Angeles to look younger, and I did, it worked. It's called maintenance and it worked. I think I'm looking younger than I did at the start of 'The X Factor' because I am eating healthier, I'm more aware of it, I'm happy, and I think if you're happy, it shows."
Louis, 63, was left heartbroken last year when Simon failed to renew his contract following 11 years on the panel but he has admitted he loved watching the series fail as a result of his exit.
Speaking to BBC Radio 2, he said: "My contract wasn't picked up last year, I was half expecting it, so it was fine because I had lots of things to do. I think being away from the show was a really good thing for me because ratings weren't good. I knew watching the first show that it wasn't going to work, so I was going, 'Yes!' I called Simon really late that night and told him what I thought, I said, 'You've messed with it too much, it's not working', and he didn't say anything for a second and then he said, 'Maybe you're right.' "
Louis will return to the show later this year alongside Simon, 56, and previous judges Sharon Osbourne and Nicole Scherzinger.
The new line-up comes after Cheryl Fernandez-Versini, Rita Ora and Nick Grimshaw stepped down last year due to a flop in ratings.
