He added: "You know she's great, she's fun and, like we say, she's like everyone's boss around here."

Keeping coy about his big plans for the day of romance, he told Entertainment Tonight: "I started a while ago but I'm not going to share that secret with you - but it's going to be good!"

Meanwhile, Jennifer previously gushed about how "special" her relationship with Alex is.

She shared: "He's so supportive. I mean, he was at rehearsal with me last night till 1am and after he had worked his whole day, I work my whole day, then we go to rehearsal and he's like, 'What time will you be done?' I said, 'I don't know.' He goes, 'Alright, I'll just come over there and I'll do some work and we'll go home together.' That's the kind of support, like in this business, it's just a different kind of business, you know, and so, to have someone who understands it and wants to be there and you want to be there for them, it's a very special thing."
