Katie Piper joked Nick Knowles didn't recognise her with her clothes off when he appeared on Loose Women today.
The DIY SOS star, 60 was on holiday with his girlfriend recently when Katie, 39, popped up at the resort in her bikini.
Joking about the awkward encounter, the panellist said: "Shall I tell the story? OK, so we are both on holiday... We didn't realise we were staying in the same resort and there's Nick behind us. Nick has done lots for my charity, I have known him for many years now haven't I?
"He has been a great friend to us all. So I thought 'I will go and say hi to him' and I wandered over, and when I am on holiday I cover up because my skin is grafted and I had a hat down to here, and sunglasses, with just a bikini..."
Katie added: "And you were on the sun lounger, in your swimwear, with your girlfriend."
Nick nodded: "Yep" while Katie continued: "I said 'Nick, hiya', and I don't think you recognised me..."
The BBC presenter replied: "Well if somebody is not where I expect them to be, I mean, I could walk past my brother and not know him in the wrong place..."
Katie said: "I said 'Hi, it's Katie Piper' and he replied he didn't recognise me, so I said: 'Well we have never seen each other without our clothes on, have we?'''
Panelists Christine Lampard, Coleen Nolan and Dame Kelly Holmes were in hysterics after the story as were the studio audience.
Nick, who split from his wife Jessica Rose Moor in 2016, was on holiday with girlfriend Katie Dadzie, 32, who he went public with in September 2021.
Katie was there with her husband Richard Sutton and their daughters Belle, seven, and Penelope, three.
Last month, the inspiring activist opened up about her 'empowering hair transplant' after suffering an horrific acid attack.
The mum-of-two, who has been awarded an OBE for charity and burns services, spoke about her procedure on Loose Women.
As the panel were discussing hair transplants, Katie revealed she'd had the operation after her attack.
"I've actually had a hair transplant and it's quite an invasive procedure," she shared.
A stunned Nadia Sawalha said: "I never knew that," while Judi Love looked on in shock.
Katie continued: "Because I lost my hair through an act of violence, my hair transplant was really empowering for me to say: 'I'm bringing it back on my terms."
