The former couple looked pretty close as they posed for photographers outside the venue in London.
Mum-of-one Chloe stunned in an electric blue trouser suit, while flashing her cleavage in a black bra. Meanwhile, restaurant owner Elliott also looked dapper in burgundy trousers and a grey suit jacket.
Chloe and Elliott's outing comes as the couple were pictured flirting at a gym.
New pictures from upcoming scenes of TOWIE show the pair getting pretty close during an intense training session, and it seems like Elliott didn't mind showing her the ropes.
Reports from the weekend also claim the once loved-up couple have turned to a psychic to help mend their on-off relationship.
Elliott and Chloe's relationship has kept TOWIE viewers gripped since they first got together last summer. Despite declaring their love for each other, the couple spilt when Chloe found out Elliott had slept in the same bed as another woman. Although he insisted nothing else happened.
Things got bitter between the pair as arguments erupted, but they enjoyed a brief reunion over Christmas before splitting again by the New Year.
Recently, viewers have seen Chloe and Elliott back on speaking terms following an explosive row in a nightclub, and their co-star Danielle Armstrong has been quick to pick up on the couple's sexual tension.
Danielle said in the last episode: "I still think there is so much sexual tension between you two!"
Chloe replied: "I think we just need to communicate. We didn't and then we went at war. If we'd just spoken it wouldn't have happened."
