Sam, 19, posted a cute photo of the couple on Twitter earlier today (13 January) while they were watching Buffalo Bill's Wild West Show at the resort.
Sam, who is on the trip with his family and close friends, invited Tamera along to hang out with Disney's most famous characters, and said he was having an "amazing" time.
Sam and Tamera were romantically linked after becoming considerably close during their time together on last year's show, which was won by Sam Bailey.
The pair kept tight-lipped about their blossoming romance but Tamera told Reveal in December: "Me and Sam are very, very close, it could be true. Anything could happen."
Sam also opened up later on about his relationship with the singer, telling The Sun, "I love her and I think the world of her." Meanwhile, Tamera gushed: "I have the most amazing relationship with Sam. He puts a smile on my face every day."
Sam and Tamera, who headed off to Disneyland Paris yesterday (12 January), have been making the most of their trip, having tours of the Magic Kingdom and the Disney studio.
Sam kept a protective hold around 16-year-old Tamera as the pair cuddled up for a photo, meanwhile Tamera was visibly beaming from ear to ear.
Essex boy Sam later told fans: "Hey guys... I'm still in @DisneylandParis and having an AMAZING time! Got bundles of photos to show you all but having trouble getting wifi."
The couple will both be on X Factor's tour along with fellow contestants Abi Alton, Hannah Barrett, Sam Bailey, Luke Friend, Rough Copy and Nicholas McDonald.
Tweeting about his excitement ahead of the tour, which will kick off in February, Sam said last week: "Getting increasingly excited about the #XfactorTour who's got their tickets???"
