But, honestly? We couldn't tell you for sure which is which...
And fans were less than impressed with Kerry's new look.
“Can’t afford school dinners one minute and saying she’s bankrupt but now seems to be able to afford this crap,” one follower slammed.
Another wrote: “Bum looks better in the before.. Looks uneven in the after???”
However, one loyal follower stuck up for I'm a Celebrity! winner saying: “She's proud of her body after having 5 kids. So what if she flaunts it and you prehistoric dinosaurs don't like it. She's not doing it for your approval...get over yourselves.”
