The reality TV star was answering questions from fans in a live video on social media app TikTok when somebody asked her the question "Why does Holly not like you?"
Price, 45, replied: "Holly Willoughby? I think she’s good friends with Pete.
"That’s why she doesn’t like me, must be. A lot of people are, as they say, 'Team Pete'.
"But who cares? I haven’t been married to the man for years."
Model Price and singer Peter Andre, 50, were together for five years after meeting on I'm A Celebrity... Get Me Out Of Here! in 2004. They share two children Junior, 18 and Princess, 16.
The couple split in May 2009 and the pair underwent a bitter divorce battle, the details of which must remain confidential after a high court settlement in 2015.
Andre has been a regular guest presenter on This Morning, hosted by Willoughby, 42, and Price has also appeared on the show as a guest on several occasions.
But fans had speculated there was tension between the two women when Price was a guest panelist on Loose Women in 2017.
Willoughby and then co-host Phillip Schofield took part in a live link-up with the Loose Women studio to ask what was coming up on the show.
Ruth Langsford told them: "We have something interesting to try, Christmas cake with cheese."
Price added: "I don't really like Christmas cake, but I'll try it."
She then added: "But Holly, I think this is for you because you're losing too much weight."
Willoughby responded: "Thank you very much," and quickly moved on.
