The former couple came to a dramatic end this year when Louise found out that Spencer had cheated on her - in her bed! However, that may all be water under the bridge if these snaps are anything to go by, since the pair look happy to be hanging out again.
Spencer and Louise stepped out yesterday evening (5 September) for the launch of close friend and former MIC star, Hugo Taylor's new eyewear collection.
Although ladies' man Spencer was accompanied to the party by current girlfriend Stephanie Pratt, it didn't stop him catching up with ex Louise on the steps of the venue and taking a couple of fun photos with her.
Louise looked pretty in a short leather skirt and a floral top, which she teamed with some strappy heels and a bright pink clutch bag that co-ordinated with her eye-popping lipstick.
Meanwhile, Spencer dressed to impress for the occasion in a navy blue jacket with black trousers and a crisp white shirt.
The former couple appeared to be enjoying their brief moment together, with Spencer pointing out that petite Louise had to stand on a step in order to be closer to his height.
Stephanie - who has been dating Spencer since summer - also looked smart in a chic black dress and eye catching pink heels.
A number of the Made In Chelsea stars came out to support Hugo's latest business venture yesterday, including Oliver Proudlock, Jamie Laing, Rosie Fortescue and original cast member, Caggie Dunlop.
And it's no wonder they were out in full force, as Hugo told Reveal this week that his sunglasses has been a huge hit with his reality TV pals.
The 27-year-old entrepreneur got suited and booted for his launch and was joined by his stunning model girlfriend Natalie Joel.
Also spotted with a female on his arm was Jamie, who posed for pictures with a blonde guest and even gave her a kiss on the cheek! We wonder what girlfriend Tara Keeney would say!
