Kate, 52, shed a staggering two stone ahead of jetting Down Under thanks to cutting back on sugar and banning alcohol outright.
Opening up on Wednesday’s edition of GMB, Richard Arnold revealed he’s seen the skimpy outfits Kate has packed for the jungle.
Gossiping to Piers Morgan and Susanna Reid, Richard said: “I’ve been privy to some of the fittings for some of the costumes that she is taking into the jungle.
“They do all have to wear the same thing, expect of course, they are allowed to take in underwear and the shower costume.”
Richard added: “The shower costume is the costume.
“It’s nipped and tucked in all the right places.
“I had a glad-eye across it. I can assure you.
“I haven’t seen a woman since 1985 like that.”
After Susanna shot down claims in the media that Kate had banned sugar ahead of her jungle stint, the ITV regular added: “She had lost a lot of weight.
“She has been off the sauce.”
Kate and a host of famous faces arrived at Brisbane airport ahead of I’m A Celeb…. Get Me Out Of Here! 2019 kicking off later this week.
The show, which will see Ant McPartlin return alongside Declan Donnelly after a year away, officially kicks off on November 17.
