So they look like they're in the throes of passion here.
And Simon Cowell has labelled them "two young kids in love".
But Eoghan Quigg and Diana Vickers are still playing coy when it comes to their relationship.
In a joint interview with Heat magazine, neither Diana or Eoghan would confirm whether they are indeed a couple.
Questioned about her feelings for the crooner, Di replied: "I can't say. It depends what happens. Right now I'm not going to think about anything like that."
In a comment that's bound to crush poor Eoghan, she added:
"I'm going to make sure I spend some time with Chris (her student boyfriend) at Christmas, and who's to say what's going to happen in the future?"
"I'm not a liar," she insisted. "I'll tell him everything to do with me and Eoghan, and I'd never cheat on anyone in my life."
However, Di couldn't contain her affection for her X Factor co-star, saying: "People look at him like he's a 10-year-old boy or something. He's not, though, at all - he's
surprisingly grown up.
"There's a difference between loving each other and being in love. I love him to bits..." she continued, tellingly.
For his part, Eoghan stayed cool in the interview. Asked about whether he'd like to hook up with Di, he answered: "It's possible... maybe... or maybe not."
But he did add that meeting Di was "the best experience" of his life. Awwww.
