"I'm really nervous," Sam tells Reveal. "I've got a cold at the minute and I'm just getting over a chest infection, but luckily the Bell's Palsy has gone now.
"It's going to be amazing being back there and performing, but then I'll have the four judges in front of me... particularly Simon!"
Former prison officer Sam, whose record deal contract runs out in just two weeks, tells us that she was "too embarrassed" to ask Simon for a picture when she popped down to the studios a few weeks ago.
"I saw Simon a couple of weeks ago when I was at the studios to watch the show. Louis Walsh was like, 'Go and see Simon', but I thought, my contract's due to finish soon so I don't want to be heckling on his door like 'Simon, give me another deal'!
"I eventually bumped into him backstage and he came over and gave me a hug. He said hello to my daughter. It was nice to see him. I didn't ask for a photo, I just left that... I was too embarrassed!"
We tell Sam that she should get a photo with Simon this weekend. She ponders: "Yeah, will do. Who knows..."
But which judge is Sam really looking forward to seeing this weekend?
"Louis Walsh! He'll just be rocking along while I'm singing. I love him to pieces. He's like the Dot Cotton of the entertainment world, and if there's ever a bit of gossip, pretty much Louis is always at the brink of it! He's just brilliant."
