OTI Mabuse admits she "feared for her life" after flying across the room in rehearsals when her Strictly partner Kelvin Fletcher tried out a dangerous lift.
The professional dancer revealed they had to simplify the risky move when it went wrong backstage.
On BBC Two's It Takes Two, Oti nervously laughed as she explained why she was left scared by the demanding trick.
Host Zoe Ball asked: "Were you in fear of your life?" to which Oti replied: "I was! Every week Kelvin starts slow, but then he progresses incredibly.
"So when we were doing it, we thought 'let's both have our hands up'. On Wednesday, he gets faster and I almost fly across the room.
"I was like, 'oh my god, don't let me go!'
