The former EastEnders stars were soaking up the sun in Turkey together and both shared posts from their romantic getaway.
In one snap actress Jessica Plummer, 29, flaunted her incredible figure, flashing her abs in a tiny purple two-piece.
Ben also shared a series of snaps and videos - showing him at one point doing an impressive backflip into the sea.
The ex-Peter Beale actor also showed off the delicious-looking food the couple had enjoyed.
He captioned his post: "The best fake birthday holiday I’ve ever had."
We first revealed the ex-EastEnders stars were dating when they were spotted sharing a passionate kiss last summer.
They had grown close after hitting it off while filming their BBC drama The Girl Before.
Ben and Jessica were pictured in a steamy clinch beside a taxi near London's Soho House and two days later they attended the screening for their new series together. (Sat 18) Views: 187
