And, although they aren't currently girlfriend and boyfriend (as far as we know!), they sure looked cosy to us...
While Chloe - looking so chic in a cream blazer coat - attended the famous event with her sister Abbey and the team at Lipsy, it wasn't long before she and ex-Jake were posing for pictures together. And wow, they looked gorgeous.
Wearing his heart on his sleeve, Jake couldn't help declaring his feelings for Chloe on Instagram alongside a picture of them both.
He wrote: "Listen true love never dies... I never give up on nothing @chloelewis91 #soulmate."
Meanwhile, coy Chloe played it safer with a simple message saying: "Look who I found @Jakehall01."
Despite trying to give nothing away, we think Chloe's smile shows she still has feelings for model and footballer Jake.
Looking at the pictures, fans commented that the pair "looked sweet together" and made "a tidy couple".
TOWIE wrapped its 14th series last weekend with an eventful and emotional episode tying up all the storylines of the season - except for Chloe and Jake's as she told him she needed more time to decide whether to take him back.
She still gave him a cheeky kiss though!
After the episode aired, Chloe said of Jake, her boyfriend of six and a half years: "I hope we can move on and forget everything that happened and start going for dinner again and spending time with each other, so we will see.
"I do think we should take things slow. There is no point rushing into things. We're still young and I don't want him to make any wrong decisions just getting back with me.
"I hope things work out good between us."
