When asked if she caught Pete's appearance on the show, the mum-of-five replied: "Why? Was he on it?"
Earlier this month, it was confirmed Katie had joined ITV's Loose Women as a regular panellist, appearing once a week on the show.
Shortly after, it was then announced Peter would be following in her footsteps. He appeared as a guest panellist on the show, along with Craig Revel Horwood, as they became the first ever men to join Loose Women.
ITV revealed the move was to spice up the daytime talk show, as having males on the panel would offer a different perspective on the topics and news discussed. The 'Mysterious Girl' singer proved to be a hit on the show, thanks to revealing a few saucy secrets of his own during his appearance.
At last night's National Television Awards Katie was asked if she thought she made a better panellist than her former flame, but choosing to compliment Peter instead, she told The Mirror: "Of course not. He's good. He talks as much as me."
Katie's comments come after Peter recently revealed things between himself and his ex-wife are now amicable.
Speaking on ITV's Lorraine, he explained: "It's really strange, even with things that have happened in the past, I mean, me and Kate are okay now."
"We see each other when we see each other with the kids. It's all nice and very civilised," he said. "We get on really well, which is excellent, so that just adds to the peace and serenity. And the kids are really happy and it's really nice."
Katie and Peter, who met in the I'm A Celebrity... Get Me Out Of Here! jungle, split in 2009 after nearly four years of marriage. They have two children together, son Junior, ten, and daughter Princess, eight.
Katie is also mum to three other children. Harvey, 13, is her eldest son, while she shares Jett, two, and Bunny, one, with husband Kieran Hayler.
Peter has too remarried since his split with Katie. He wed wife Emily MacDonagh in July last year and the couple share a daughter, Amelia, two.
