Abbey made the confession this morning, adding that footballer Peter has even helped her at home with some complicated lifts.
Speaking on BBC Breakfast, Abbey said: "[Peter] loves it! He absolutely loves coming to watch. Aljaz has taught him a few steps.
"I was practicing some lifts with him the other night, which was quite funny. There was nearly a few injuries!"
Aljaz also appeared on the morning show and, speaking about his secret lesson with Peter, laughed: "It was just a casual Wednesday!"
The professional dancer added: "I think he has a talent, I think he definitely has a talent for it."
Abbey continued: "He's actually quite jealous as he loves dancing. I think he'd definitely do [Strictly], especially after me going on about how much fun I'm having. I'm having the time of my life."
While chatting on the sofa, Abbey also revealed that her feet have been taking a pounding due to the dance shoes which she has to wear.
"We have to wear Latin or ballroom shoes, which are the most uncomfortable shoes in the world even though they're about a one-inch heel," she said. "I'm used to five inches!"
