Enjoying a fun-filled evening out in the capital's nightspot DSTRKT London, Elliott looked pretty pleased to bump into his fellow celebrities.
And flashing his pearly whites, the reality star made sure to capture his night on camera.
Taking to Instagram, Elliott posted a photo of himself and Gary posing with Wayne and Coleen Rooney. Alongside his photo, he said: "Nice to meet @WayneRooney too!! #Captain."
In another snap, the Essex regular told fans he had had "such a laugh" partying with Geordie Shore star Gaz.
Elliott is pictured getting a kiss from the Geordie lad and we think he looks pretty chuffed to have Gaz puckering up to him, don't you?!
The boys bumped into each other following Gary's busy day in London with his Geordie Shore castmates, promoting the show's new series.
Following their day of causing chaos in Hyde Park, Gaz then joined his co-stars Aaron Chalmers, Kyle Christie and Scott Timlin for a night on the town - clearly unable to resist a jagerbomb or two!
Meanwhile, Elliott may have been partying solo yesterday, but he and ex-girlfriend Chloe Sims have recently fuelled speculation they are getting back together again.
The pair split for the second time earlier this year, but after growing closer again, it seems their relationship could be back on track.
In last night's TOWIE episode, viewers saw the on/off couple flirting up a storm during James Lock's club opening.
When Danielle Armstrong commented that the pair were looking very loved-up again, neither Chloe or Elliott gave anything away, choosing to smile coyly instead.
Are they? Or aren't they?!
We guess we'll have to wait and see...
TOWIE continues this Sunday 15 March at 10pm on ITVBe.
