Speaking on Tuesday's episode of her podcast The Buzz, Keira, 32, told her co-hosts: "I just don't know if she's worthy of being The Bachelorette."
Keira added: "[Angie is] a boy's girl. I can tell her character, she's the kind of girl that you would want to be mates with if you were a guy."
"She probably won't end up with anyone. And if they do, they'll probably end up as just friends."
Keira added: "I honestly think that a girl that should be The Bachelorette should be desirable."
It seems this is a personal vendetta for Keira, who revealed on her podcast that she hasn't been a fan of Angie's since the former Goggleboxer criticised Maguire's behaviour on the 2016 season on The Bachelor.
"[Angie's] opinions of me haven't been very nice in the past.
"I just remember I don't like her and I don't remember the reason. Just a few things she said about me."
Prior to Keira slamming the new Bachelorette, Angie made her feelings known about Bachelor In Paradise alumn in a series of catty Instagram comments.
After someone on Instagram suggested that Jared should go on the new series of The Bachelorette, Angie had just this to say.
This could be the start of a very unexpected feud.
