STRICTLY hunk Kelvin Fletcher's routine was so sexy it had judge Motsi Mabuse speaking German by accident.
The former Emmerdale man shook his snake hips to Elvis Presley's Jailhouse Rock, leaving Motsi flustered.
As she tried to critique his dance, she said: "He made my life, not my day! Oh my god Kelvin - what was that? I can't believe it.
Motsi became tongue-tied and accidentally spoke the different language, prompting her to say: "I'm speaking German man, you killed me.
"Well done, that was out of this world!"
The pair dazzled with their jive, which saw them bag 39 points from the judges - and joint first place on the leaderboard, alongside Karim and Amy Dowden.
They secured ten points from Motsi Mabuse, Shirley Ballas and Bruno Tonioli, with Craig giving nine points.
Speaking about the dance, head judge Shirley said: "I'm speechless, I don't know where to start but I do want to mention your flicks and your kicks, contra body, opposite arm to foot all the way through.
"Your coordination was superb, that's all I can say about that. You mixed your swing, you had some jive, you had great action."
After the show Oti revealed she broke down in tears when Kelvin surprised her by bringing her mum to watch them dance.
Blackpool is one of the most important dates in the BBC show's schedule and pro Oti admitted her mum hadn't watched her dance for Strictly before.
So in order to mark the occasion, the soap star decided to bring her along.
Oti shared the news on Instagram with a photo of Kelvin's sheepishly smiling as they drove up on a first class train to the northern city.
She captioned it: "Wow! I don't even know where to start. Before we did our walk @kelvin_fletcher told me to look over the corner had a surprise for me, turns out he brought my mom and god-mom to blackpool.
"My mom has NEVER EVER seen me dance live on Strictly before and I just broke down in tears.
