Attending Benefit's 'Curl's Best Friend' Pop-Up Curl And Cocktail Parlour in the capital, the cute couple certainly didn't come over all camera shy.
With only eyes for each other, Steph and Josh couldn't care who was watching as they engaged in a little PDA.
Captured kissing on camera, the reality stars looked like the perfect pair at the showbiz bash.
While Josh looked dapper wearing a denim shirt and fitted coat, Stephanie looked ulta glam in a glitzy one-shoulder dress and studded courts.
Looking very bronzed, the former Hills star sported perfectly styled locks finishing her look with plenty of kohl eyeliner and a hot pink gloss on her lips.
She and her beau were joined at the event by their co-stars Louise Thompson and Tiffany Watson, as well as some of our TOWIE faves - including Lydia Bright, Lauren Pope and Jessica Wright.
Earlier this month, Stephanie returned from LA where she had enjoyed a long break visiting family and friends.
Landing back in London, the blonde beauty was more than happy to be reunited with boyfriend Josh, and the pair have since been settling into their new home after moving in together.
The couple first began dating last year - after Josh joined the MIC cast - and it seems Steph is pretty smitten with her other half.
So much so, that she recently told fans she felt like "the luckiest girl in the world".
