The TOWIE star was gorgeous in a black silk slip dress and duster jacket as she left the exclusive LouLou's club in London on Wednesday night (8 June).
Kourtney and Lindsay were also at the club that night.
Chloe was accompanied by Robert Tchenguiz, the businessman she's been romantically linked to in the last few weeks, after they were seen together at the Cannes Film Festival.
But in an interview with TOWIE co-star Bobby Cole Norris in May, Chloe insisted: "I'm still very much single. No plans to change it anytime soon. I'm just loving life."
Meanwhile, a rep for Chloe has said: "They aren't dating. Chloe is very close to Robert's sister, Lisa, and they are all hanging out and having fun together in Cannes."
We wonder if Chloe managed to grab Kourtney for a chat last night? She could have broken the ice by saying she'd met Kourtney's mum Kris Jenner in Cannes!
Chloe was attending the lavish de Grisogono party.at the iconic Hotel du Cap-Eden-Roc, when she realised Kim was sitting at the next table alongside her mum Kris Jenner and Kourtney Kardashian's on-off boyfriend Scott Disick.
She totally FREAKED OUT on Snapchat over Kim before managing to grab Kris for a photo!
