Fans noticed the intense chemistry between the two.

Viewers were left in awe after John Whaite and Johannes Radebe danced their way to the top of the leader board in Saturday night's episode of Strictly Come Dancing. The Bake-Off star and his dance partner stole the show with their stunning Argentine Tango, with the ever-harsh judge Craig Revel-Horwood branding it "fantastic". The pair scored a whopping 39 out of a possible 40. https://twitter.com/bbcstrictly/status/1464683770523443206

Cynthia Erivo, who stepped in for Motsi Mabus - who was missing this week due to a Covid close contact- clapped and said: 'I was crazy for it... this is gorgeous'

'They are back! Fab-u-lous," Shirley Ballas added.

John and Johannes received 10s from all the judges except for Craig, who gave them a nine - but they still topped the leader boards, which saw Tilly Ramsay and partner Nikita Kuzmin at the bottom. Thanking the judges for their comments and feedback, John said his bond with Johannes was stronger than ever and that the pair had a "great relationship". "I know I had a bit of lull last week, I was struggling to find myself. I thought I have to perform up and we just found me again, we found us again this week," he said. "We said it's me and you, and nothing else matters. I feel like I’ve been reborn, darling.” Fans took to Twitter to praise the performance and point out the chemistry between the two. "That Argentine tango from John and Johannes was amazing. Definitely saved the best dance of the night until the end." one person wrote. "John and Johannes tonight on Strictly Come Dancing...OMG superb, intense, beautiful choreography, incredible chemistry. I so want them to hold that glitter ball," another said. "The chemistry is back, hello John and Johannes!" a third added. "OMG John and Johannes on @bbcstrictly I so want them to win. Incredible tango, chemistry,"another said. "John and Johannes are the best pair of the year by FAR. They never make a single error, have perfect chemistry and the talent is off the scale. If they don’t win I will riot!" a fifth tweeted. Meanwhile, AJ Odudu and Kai Widdrington came in second place, dancing a Couple’s Choice.
