Over on Twitter, Jodie replied to a fan who shared a photo of Katie's natural teeth, which have been shaved down to allow for pristine veneers to be fitted.
They wrote alongside the snap: "I remember when I was in school and the lads used to love Katie Price and I used to say nah she's trash and I said Jodie Marsh was 10 times better. Well, who's got the last laugh now?"
As well as tagging both of the models' official accounts, the user added a green-faced sick emoji.
Jodie replied with a string of crying laughing emojis.
The scary photo came from Katie's YouTube channel, after she revealed an insight into the process of veneers.
The mum-of-five joked about the shocking look herself, saying: "I'm feeling good. Just numb. I look like something out of James Bond. The man with metal teeth."
It isn't known for sure why she and Jodie don't get along, however they have exchanged a number of swipes over the years.
Back in 2011, Jodie suggested it was her rise to popularity that caused major tension with Katie.
She told Now magazine: "I've never known her to be pleasant. I think that when I got famous, she felt threatened by me because before I came along, she was the only big name in glamour modelling."
However she hasn't particularly tried to make things nice between her and Katie.
In 2009, Jodie really didn't hold back when she told lads' mag Zoo: "She's not good in bed – she doesn't know what she's doing. She's as cold as ice, she's got hardly any friends and she's thick as s***. I think anyone who wants to be with Jordan is a bit weird in the first place."
And she even went as far as suggesting that Katie's third husband Kieran Hayler tried to get with her before Katie.
She told Heat magazine: "He was obsessed with me. There were a lot of people saying to me, 'Oh he really likes you Jodie, why don't you follow him and give him a chance?' And I felt a bit pressured to follow him back.
"I did but only for a short time because his messages were incessant. I started to believe he was just one of these 'party boys' – boys who just wanted to get with someone to get famous."
Katie has also taken swipes at Jodie though, previously hitting out and comparing Jodie's nose to a "builder's elbow".
She also said that Jodie "sh***ed nearly all my leftovers and not one of them wanted you".
But Jodie bit back, saying: "Who? Oh yeah, her – the one who's famous for having loads of different kids with different dads!"
It seems there's no love lost with these two.
