Alesha Dixon has lashed out at Natalia Kills, calling the singer a "vile human being".
The star revealed she was happy to see the former X Factor New Zealand judge fired from the show last month, after she launched a tirade of abuse against a contestant and accused him of copying her husband and fellow judge Willy Moon.
Speaking at the 'Britain's Got Talent' launch, Alesha told BANG Showbiz: "It was absolutely disgraceful. I watched it back because I heard so many people talk about it and I just thought it just showed what a vile human being she is. I mean, honestly, who can sit there and do that and get away with it? Well, she didn't, she got fired. Good, it was disgusting."
While the 'Breathe Slow' singer isn't a fan of Natalia's approach to judging, she has confessed that her fellow 'Britain's Got Talent' judge Simon Cowell has become much more "laid back" since his girlfriend Lauren Silverman gave birth to their son Eric in February 2014.
Alesha said: "He's more laid back in himself. He's still quite honest and direct as a judge, but I think that's what we like about him, and why the public fell in love with him, because he's the person who says what you're thinking, whereas some of us would be a bit more tactile and sensitive. Simon just hits it straight down the line and I like that about him, so he still is that guy but I think he's laid back now."
