Here's a look at the Strictly Come Dancing celebs in their very first performance.
This year we've fifteen celebrity contestants and tonight's launch saw them partnered up with the pros.
In 2017, the pro line up has seen a bit of a switch up with some new names.
Joining Strictly are champions from the Ballroom and Latin world; Dianne Buswell from Australia, Nadiya Bychkova from Ukraine and Amy Dowden from Wales.
They join Strictly alongside the returning male dancers Anton Du Beke, Brendan Cole, Kevin Clifton, Neil Jones, Pasha Kovalev, Gorka Marquez, Giovanni Pernice, AJ Pritchard and Aljaž Škorjanec
Plus returning female dancers Karen Clifton, Chloe Hewitt, Katya Jones, Oti Mabuse and Janette Manrara.
However both Neil and Chloe won't get a celeb partner, instead only appearing in the pro routines and acting as standbys in case of any injuries.
Tonight, the remaining 15 pros found out their celebrity partners.
The couples started off with Mollie King & AJ Pritchard, Susan Calman & Kevin Clifton, Alexandra Burke & Gorka Marquez, Charlotte Hawkins & Brendan Cole and Ruth Langsford & Anton Du Beke.
More confirmed pairings from tonight's launch show are Simon Rimmer & Karen Clifton, Chizzy Akudolu & Pasha Kovalev, Debbie McGee, & Giovanni Pernice, Gemma Atkinson & Aljaž Škorjanec and Aston Merrygold & Janette Manrara.
Finally, rounding off the pairs are Reverend Richard Coles & Dianne Buswell, Davood Ghadami & Nadiya Bychkova, Joe McFadden & Katya Jones, Jonnie Peacock & Oti Mabuse and Brian Conley & Amy Dowden.
Now all the celebs and pros have two weeks of intensive training before they have their first LIVE performance on BBC One at the end of the month.
And before long, it'll be time for the first elimination of the series.
