Joe Sugg invited all the Strictly Come Dancing celebrities to his house to watch first show of the series

The Strictly celebrity invited his fellow Strictly contestants and pro dancers over to his house to watch the show for his 27th birthday.

Because the first episode is pre-recorded, this is the only chance the Strictly celebrities will have to chill out and watch themselves in action.

While fellow celeb Katie Piper shared a picture of her "partying with the pros" at Joe's house. Wonder whether she was able to pick up any extra tips?
