Kate's doting partner - who was joined by their kids Darcey, 13, and William, 10, in Australia - also gushed about the presenter's "knockout" appearance following her recent two-stone weight loss, enthusing he's fallen in love with her "all over again".
Heaping praise on the blonde, a delighted Derek shared: 'I'm falling in love with her all over again, you see how amusing and kind she is.
Despite rooting for their mother to take home the crown, Kate's daughter admitted she believes sports pundit Ian Wright has "got it in the bag".
"So I am the victor really". "It says, "Watch out mate, anymore of that and I'll let loose".
In awe: Heaping praise on the blonde, a delighted Derek shared: "I'm falling in love with her all over again, you see how amusing and kind she is".
Jacqueline said: "I didn't realise they were good looking and then we said what one would you have, she said Dec and I said Ant at the same time". She had a towel round herself.
"And I do wonder if by the end we will see the whole bikini".
At first the radio presenter was flattered, telling the Bush Telegraph: "That's good to know because I think when you approach 50 it feels like you are no longer attractive".
Earlier this week, Darcey and Bill admitted they would rather have Kate's campmate Myles Stephenson as their dad rather than Derek.
He admits he's slept with women much older than Kate Garraway before confessing his feelings for her. Jacqueline asked Myles to which he coyly replied: "Yep".
Jacqueline asks, "And you've slept with someone older than your mum?"
She then continued on to say that she thinks Myles was just being kind and that it "was his charity work for the year!"
After Lorraine commented that Kate has never looked better, wearing no makeup in the jungle and showing off her fabulous figure in her swimsuits, Derek agreed: "Absolutely. Me or Myles?" and without hesitation both kids said Myles with Darcey adding: "Hands down!"
