MARRIED At First Sight UK stars Lacey and Nathan narrowly avoided a run-in after attending the same event on Friday night.
Nathan and Lacey were matched on the E4 experiment, and appeared to make it work, but split shortly after filming ended.
Shortly after that, their split got bitter, with Lacey accusing Nathan of faking their relationship for the cameras on the show.
On Thursday night, the pair faced running into each other for the first time in weeks as they hit London town for an event.
Attending the Garnier Method for Curls event at Phonica Records in London, Nathan arrived on the arm of new girlfriend, Love Island's Abi Moores.
The pair co-ordinated in cream and grey outfits, later posting videos of their time at the event online.
Dancing and sharing a kiss, the pair kept themselves towards the back of the room while watching musical guest Craig David perform.
Meanwhile, up near the front of the stage was Lacey, who looked dressed to kill in a plunging red bodysuit and patterned netted tights.
Wearing her long brunette locks poker straight over her shoulders, Lacey danced the night away with her pal, later sharing her own adventures from the night.
Lacey and Nathan's bitter split has taken several turns since cameras stopped rolling on MAFS, with Nathan initially claiming at the reunion that Lacey had proposed a 'showmance' for the sake of brand deals.
Lacey later hit back saying that he was unsupportive in their relationship, refusing to cheer her on during a Race for Life in aid of cancer research.
Nathan later broke his silence on the break-up and claimed he was in fact the one who has been left "brokenhearted".

Speaking exclusively to The Sun, he said: "Things weren’t the same off the show, it was very different.
"I’d always have to go there, she wouldn’t come to see me – those kind of arguments. I’m not too sure, things were quite different after the show.
"When you’re together, you’re 100 per cent in the same place.
"But after the experiment there was a big distance there.”
At the beginning of April, Nathan announced he had officially asked Love Island star Abi to be his girlfriend, using a lavish proposal to do it.
The couple were introduced by mutual friend Reuben Collins, 24, who starred on Love Island alongside Abi.
Putting on a lavish display for Abi's 27th birthday, Nathan splashed out on a stunning stunning ring in order to ask her the all-important question.
