Strictly's Jamie Borthwick ended up being kicked in the head as he rehearsed for Saturday night's show.
The EastEnders star, 30, is paired with Michelle Tsiakkas for the current series of Strictly Come Dancing.
They will be dancing the Rumba to Bill Withers' Ain't No Sunshine this weekend.
Actor Jamie took to Instagram to share a clip from rehearsals - revealing at one point it went very wrong.
Professional dancer Michelle, 29, attempted a handstand behind Jamie which resulted in her kicking him in the head.
Jamie was then seen stumbling backwards after almost falling over his partner.
Writing in the comments section, one fan said: "I’d like to see that kick to the back of the head in slow motion. Poor Jamie but hahaha."
Another wrote: "The way I went from LET’S GO 🎵🙌🏾🙂 to 🙊😂 his poor head!"
Some fans previously insisted Jamie has an unfair advantage in the competition after winning last year's Christmas special.
After it was revealed he'd be taking part in the current series, many fans joked that Jamie is definitely going to win because of his previous stint.
Writing on social media, one said: "Ladies and gentlemen, we have our winner."
Someone else said: “We've seen on the Christmas special that he's a great dancer. I'm predicting he'll be a finalist. He might even win"
“The pattern in Strictly tends to be the alternate gender winning from the gender the year before. Ellie won last year, prior to Ellie, Hamza won, prior to him, Rose won.... you get the drift.”
Another person questioned: “Then why did he do the Christmas special if he was just going to do the main show anyway??"
