To be fair, almost every Strictly professional does a tour during the off season for many years. Anton does a tour with Erin (who used to be on the show), there's a here come the boys tour with Giovanni, Aljaz and Gorka. AJ has his own tour, as does Giovanni. I think Brendan does, or used too. Kevin and Karen did theirs last year (and before they split up). Aljaz and Janette have their own tour. Neil and Katya have one. If memory serves right, Oti did a tour with Iain Waite a couple of years ago. Robin Windsor had a tour. Flavia and Vincent do their's every couple of years. Trent (who was only on the show for a year - but does choreography now), does a tour with his wife. There's also a Burn the Floor tour that a lot of the Strictly lot start off on.
There are varying reports about what the professionals earn, most suggest around £30,000 per series, which does go up once signed for the tour. (The celebs money increases depending on how far they get in the show, "standard £25,000 payment for signing up", quarter-finals - their fee jump to £60,000, £75,000 for semi-finals and £100,000 for the winner.
The judges earn between £150,000-£199,999.
