It's not all smiles in the Strictly studios this weekend.
Holly Valance's professional dance partner Artem Chigvintsev has had to pull of out this week's competition after hurting his back.
Doctors have ordered the professional dancer to take a break and get some rest.
Professional dancer Brendan Cole, who got the boot last week will be stepping into Artem's dance shoes to partner Holly on Saturday's show.
Artem tweeted that he was "sad not be dancing with Holly this week but was really grateful to Brendan for quickstepping in".
Holly added: "I'm obviously disappointed I won't be dancing with Artem this weekend, but his wellbeing is very important to me."
Brendan left the show last week after being voted off with his celebrity partner Lulu.
