They decided to part ways a year ago after an on/off relationship but remain close friends.
And Ellie Goulding sent tongues wagging as she joined her ex flame Dougie Poynter at Burberry's Love Magazine party on Monday, shortly after attending the Dame Vivienne Westwood and James Jagger's Mad Max bash.
The pop songstress, 30, looked very busty in a skin-tight dress as she joined the former Mc Fly singer, 29, for a cosy display during London Fashion Week on Monday - with them leaving the party together as well!
She teamed the look with a pair of towering black heels, while her blonde tresses, which framed her autumnal make-up look, effortlessly caught the wind.
The starlet flashed a red Tibetan inking on her wrist which sat underneath a gold wristband.
Hot on her heels was her ex Dougie who rocked a printed button down top, which he teamed with a pair of skinny black jeans and an edgy biker jacket.
The former boyband star sported his signature unkempt side-parted tresses as he caught up with his former flame.
The exes seemed to be having a whale of a time at the event that also drew out the most in-demand models in the world - Kendall Jenner, Bella Hadid, Winnie Harlow and Lily Donaldson. And Kendall Jenner was, of course, the guest of honour looking fly in a slinky slip dress, tough girl ankle boots and this rather gorgeous couture cape which came straight from the Burberry catwalk. It looks super cosy and ideal for throwing on over a skimpy frock.
Or you can recreate Kendall's look with one of the capes in our edit below.
Meanwhile, earlier on in the night Ellie and Dougie continued to prove they were very much the friendly exes as they arrived in style at the Dame Vivienne Westwood and James Jagger's Mad Max party.
The beauty flashed her toned legs in a suede dress, while the former Mc Fly singer looked every inch the rocker for the event held in aid of climate change.
Ellie looked very much the blonde bombshell in the casual, yet sexy garment, which was buttoned down the middle.
The pair shunned any signs of awkwardness as they sat together at the fun-filled fashion party after splitting in February 2016.
