The reality star posted a snap of her and Jake sharing a kiss while on holiday in the Dominican Republic.
Captioning the photo, Lauren included a yellow heart emoji and the word "#one".
The couple jetted off on a getaway last week and it looks like it's been quite the idyllic trip full or sunbathing, relaxation and romantic dinners.
The couple took a break in their relationship in October, but Lauren confirmed they had decided to give their romance another go a month later, and it looks like things are now firmly back on track.
Lauren was last seen on screen on the 16th series of The Only Way Is Essex, where she made a brief return to the show and filmed scenes with Chloe Sims.
She showed off her recent weight loss on the show and revealed how she had felt happier than she's ever been. In December, Lauren also released her fitness DVD called Lauren's OMG! Workout.
