The singers were pictured relaxing on a sofa, with a make-up free Tamera resting her head against Sam's chest.
Sam posted the photo to Twitter, telling fans: "As promised! Samera selfie."
Sam and Tamera were romantically linked after becoming considerably close during their time together on last year's talent show.
At the time, the pair kept tight-lipped about their blossoming romance, but they're still going strong and last month even enjoyed some quality time together during a trip to Disneyland Paris.
Sam and Tamera, along with fellow contestants Abi Alton, Hannah Barrett, Sam Bailey, Luke Friend, Rough Copy, Nicholas McDonald and winner Sam Bailey, will be performing on a UK and Ireland arena tour starting this month.
They'll kick off on 15 February in Belfast before wrapping up in Birmingham on 29 March. Sam, 19, tweeted last night: "Rehearsals went great yesterday... back in tomorrow. #XFactorTour."
