Strictly Come Dancing judge Motsi Mabuse was left speechless after Kelvin Fletcher performed with her younger sister Oti, 29, on tonight's show.
The pair danced the Jive with a very sexy and steamy routine and Kelvin, 35, managed to impress.
And as a result, Motsi, 38, was left flushed and began speaking in German as she was completely lost for words.
When asked by TV host Tess Daly on her thoughts, Motsi couldn't hold it in, and burst out: "He made my life, not my day! Oh my god Kelvin - what was that? I can't believe it."
The star - who could barely string a sentence together - then added: "I'm speaking German man, you killed me.
"Well done, that was out of this world!"
But he didn't just impress Motsi, as Shirley Ballas, 59, had her say too.
She shouted: "I'm speechless!" adding she didn't know where to start before praising him for performing the routine perfectly.
Tess also gushed over his incredible performance, saying: "You really did just make Blackpool rock, by the way."
But if there was one person to ruin it - it would of course be Craig Revel Horwood.
He said: "I thought the chassés could of been a bit lighter actually," as the audience and judges booed him.
"I've got some good things to say if you want to hear them," he continued.
However Craig did approve of the strength and stamina put into their feel-good routine.
The dancing duo performed to Jailhouse Rock together as Kelvin's nan was watching in the audience.
Oti's mum joined to watch the professional perform live on the show for the first time.
Kelvin and Oti went on to achieve the highest score tonight - bagging 32 points in total.
