The so-called 'Strictly curse' has long been talked about, but does it actually exist?
Well according to pro Janette Manrara, maybe - if your relationship isn't strong enough.
She told the Daily Express newspaper this week that Strictly Come Dancing isn't going to split up couples who are meant to be together.
And Janette should know, currently engaged to another of the show's pros, Aljaž Skorjanec.
"If you have a nice strong relationship and your feet are planted on the ground when you come in to the show, it’s not going to happen," Janette said.
She continued: "We’re engaged and happily in love and we’ve both danced with people that have been married and nothing’s ever happened. So I think when that happens it’s coming from people that maybe already have a few things going on that they haven’t realised.
“Strictly brings out the hardest part of you – for the celebrities especially. You’re put up against the wall, having to do something you’ve never done before, with four cameras in the room and millions of people watching. People don’t realise the pressure and intensity they take on."
Janette went on to suggest that the Strictly curse wasn't always a bad thing, resulting in many new romances, most recently Georgia May Foote and her pro partner Giovanni Pernice.
Janette said: "You can spend more than four hours together in the rehearsal room every day and sometimes things get mixed up about what’s real and what’s not.
"But there have been some successful relationships that have come from it.”
Strictly Come Dancing will return to BBC One later this year, but will we see any more from the 'curse'?
