Their tumultuous nine-month relationship came to an end in July, earlier this year.
But since their split, Lottie Moss, 19, and her ex-beau Alex Mytton are often crossing paths, thanks to sharing the same friendships, and Friday night proved to be no exception as they both attended the launch of Mahiki nightclub in Kensington.
However, the evening proved to be something of an awkward affair for the former flames, as both were spotted getting close to mystery companions just a stone’s throw away from each other.
Lottie and her mystery man appeared to put on an amorous display, as they stepped outside the lavish venue for a cigarette.
He was seen with his arms wrapped around the model and appeared to be smooching her neck while hugging onto her waist. Unfazed by the attention, Lottie seemed to continue her conversation with another party-goer, as her companion showered her with affection.
However, it seems their display didn’t go unnoticed by Alex, who appeared less than impressed just inches away from his ex-girlfriend. He, meanwhile, was spotted in the company of a mystery brunette and was spotted clutching onto his phone while seeming distracted.
MailOnline have contacted representatives for both Alex and Lottie.
Made In Chelsea star Alex was casually clad for his evening out in London and stepped out sporting a dark pair of jeans and a plain grey t-shirt.
Lottie, meanwhile, showcased her slender frame in a thigh-skimming mini dress, making sure to show her ex-boyfriend exactly what he is missing.
She donned a Clueless-inspired ensemble that paired together a Nineties style fur-trim Bardot minidress and diamond choker.
Her scant number left her pins firmly on view and drew attention to her bare decolletage, with Lottie wrapping up against the November chill by sporting a black heavy-duty leather jacket.
Letting her stylish dress do all the talking, the model added height with a towering pair of black stilettos and styled her platinum tresses in a poker-straight style, with her locks falling past her shoulders.

Lottie is often seen partying up a storm across London, where she has built up friendships in the Made In Chelsea set and met her ex-boyfriend Alex.
Since splitting, Lottie and Alex have proved there is no bad blood between them after being seen partying together in recent months.
Their nine-month relationship came to an end in July amid ‘cheating claims’ after a ‘rocky’ few months.
A source told The Sun at the time: ‘Alex has been away all summer filming for Made in Chelsea in Ibiza.

‘They haven’t spent as much time together as they would have liked to but things have been rocky for a few months now.
‘Alex is very fond of Lottie and they may find a way to work through their differences but for now they’ve definitely called it quits.’
The striking blonde was scouted for her first modelling agency at the tender age of 13.
Lottie first courted the attention of the modelling world when she attended her older half-sister Kate’s wedding to Jamie Hince in 2011.
The Sussex native has gone onto land campaigns with Calvin Klein and Bulgari, as well as fronting the cover of Vogue Paris in 2016.
