Brie and Nikki Bella used to break up with each other's boyfriends.
The 'Total Divas' star didn't like having to end their own relationships and so made a pact that each other would dump their boyfriends so that they "never felt bad" about it.
Nikki shared: "When we were younger, and you know how you'd have a boyfriend for like two weeks, and you'd break up with him, and it was like, we'd feel really bad.
"So, we would break up, like if I wanted to break up with a guy, Brie would do it for me, and then vice versa and it was amazing because then we never felt bad. 'Hey, you're like super nice and all but it's not gonna work out. OK, cool. Bye.'"
Whilst Brie added: "Oh, it was just like, 'Not gonna work, bye.' It was very quick."
And Nikki loved how easy it was because they didn't have the emotional connection.
She confessed to the New York Post's Page Six column: "We said it would just be great because we wouldn't, like there'd be no hesitation. It would be like two minutes, it would be great."
Nikki recently split from her fiancé John Cena but is convinced he is still her "Mr. Right".
Asked if she thought they would reunite, she said recently: "Only time can tell. I definitely do [think we will get married]. I think he's Mr. Right. He's Prince Charming. He's an amazing man. I hope that our paths do come back together and I think they will ...
"Before I do say those vows and walk down that aisle, I just don't want to be hesitant. I don't want to be regretful. I think when you sacrifice for so long, it's like, you can give so much and then you kind of get tired of giving. And then someone wants to give it back and you just already feel exhausted. I definitely have hope for the future, I really do."
