Lucy Alexander, 48, worked alongside Martin Roberts, 55, on Homes Under The Hammer for 13 years, up until her exit in 2016.
They reunited for the first time on TV yesterday as they both featured on Kirstie’s Celebrity Craft Masters.
The pair got stuck in to decorating and showing off their craft skills, in an attempt to be crowned the winner.
Whilst making a geometric candle on the Channel 4 show, Lucy got distracted as she begun to delve into Martin’s life.
“I can let you into lots of secrets about Martin,” she spilled.
Unable to keep the information about Martin to herself, Lucy asked her craft expert: “Shall I just tell you?”
She went on to divulge: “I do love him but on a filming day together, he would quite often have to borrow my make-up.”
“He would take it off me and…” Lucy said before showing how Martin would apply blusher to his cheeks.
The mother-of-two went on to win the candle challenge, along with one other, but Martin came out on top in the last two tasks, and ended up winning the competition.
The former I’m A Celebrity… Get Me Out Of Here! contestant couldn’t help but gloat about being victorious.
He uploaded a snap of himself and Lucy to his Instagram, which he captioned: “Who’d have thought it. I WON!!!”
Martin added: “Really great show. Hope you enjoyed it. Thanks @kirstiemallsopp.”
The Homes Under The Hammer presenter recently joked Lucy was up to her “dirty tricks” on the Kirstie Allsopp fronted programme.
He told Express.co.uk about reuniting with his former co-star: “It was really, really lovely [to work with Lucy].
“She was up to her same old tricks, cheating of course, and she biased the judges using very dirty tricks!”
Martin continued: “It was nail-biting! She’s hugely competitive!”
Martin revealed he has remained friends with Lucy since she left Homes Under The Hammer, and said it was great to reunite for the Channel 4 programme.
Addressing their friendship, Martin divulged: “We have kept in contact and have seen each other on several occasions.
“We worked together for 13 years so we will always be good friends! It was nice working together again.”
Kirstie’s Celebrity Craft Masters continues today at 5pm on Channel 4.
