The 'Britain's Got Talent' judge spoke out after Katie attacked new mums.
Alesha gave birth to her daughter Azura four months ago and is furious with the former 'Apprentice' star who lashed out at Lily Allen during an interview with Heat magazine.
Katie claimed becoming a mother for Lily "largely involved gaining two stone and looking pretty hideous".
Understandably, Lily was NOT happy after reading Katie's comments and took to Twitter to defend herself, explaining that she found comfort in food after miscarrying her first child.
Now Alesha has weighed in on the fight in this week's New! magazine, saying: "Katie Hopkins is just a b*tch."
Adding: "Katie shouldn’t criticise new mums.
"I haven’t done any exercise, I haven’t had time! I don’t put pressure on myself — I’m not that kind of girl...
"My priority isn’t losing weight, it’s looking after my little girl. I do love working out, though. When I’m ready I’ll start again."
