The couple, who were once engaged, were thought to have rekindled their romance at the beginning of March.
Joey, 23, posted the cute photo to Instagram last night (31 March), in which he lays in bed topless while snuggling up to Sam. In the snap, a make up free Sam beams as she stares straight on at the camera.
Recent reports indicated that Sam and Joey had given their relationship another go following Sam's recent diagnosis with Crohn's Disease.
The pair have also been pictured out together numerous times, the last being two weeks ago when they were seen holding hands on a romantic date.
Earlier last month, Joey played down reports that they had got back together but was full of praise for his former fiancée and hinted that a reunion was likely.
Speaking on Loose Women on 10 March, the Educating Joey Essex star said: "I'll always care for Sam. Always. All my life. She's a lovely girl and we spent a lot of time together in our years. We've always loved each other and stuff.
"We're just seeing how things go and I'm just there for her to keep her happy."
Reality stars Sam and Joey got engaged in May last year but sadly split some weeks later.
Despite viewers thinking that they would rekindle their romance, they called it quits for good just before Joey headed into the Australian jungle to appear on I'm A Celebrity... Get Me Out Of Here!
Elsewhere, this week it has been revealed that Sam will be taking a break from TOWIE, but is thought to make a brief return when her pregnant sister Billie gives birth in the summer.
