Did you spot these stars?
It was a big night for Strictly Come Dancing, as the contestants, professional dancers and judges all headed off to the home of ballroom dancing - Blackpool!
And it definitely didn't disappoint, as the likes of Debbie McGee and Gemma Atkinson wowed viewers with their incredible routines.
But as well as being impressed by the standard of dancing, eagle-eyed Strictly fans couldn't help but notice a whole host of celebrity guests in the audience.
And one particular famous face that really got people talking on social media, was Harry Potter creator JK Rowling who was there backing Scottish comedian Susan Calman.
After Susan took to the floor to perform a Paso Doble with her partner Kevin Clifton, she revealed her 'geek gang' were watching – with the camera panning to JK Rowling clapping for her friend.
Taking to Twitter, one fan said: 'Is that Joanne Rowling?!! Talk about #squadGoals - #strictly'.
With another writing: 'I too want JK Rowling in my squad #Strictly #scd'.
And Rowling wasn't the only one who took a trip to the world famous Tower Ballroom on Saturday night, as fans also spotted Sir Lenny Henry and Graham Norton in the audience as well.
Which caused quite the storm on Twitter, as one viewer asked: 'Graham Norton is that you in the audience? #Strictly', while another shocked viewer added: 'I’m watching #Strictly and Lenny Henry just appears on'.
Meanwhile, comedian Peter Kay also made an appearance on the show to promote his first live tour in eight years.
The 44-year-old was invited to replace host Claudia Winkleman backstage to read out the terms and conditions of the public vote.
But not one to miss an opportunity, Peter disregarded the autocue and told viewers: 'And for the first time in eight years Peter Kay is going on tour.'
Only in Blackpool!
