But now the bands have said they have had to change their tour dates a bit.
The girls and boys will now kick off their tour on 1 March, not 28 February as they originally planned.
Their first date will still be at Birmingham's NEC Arena.
The tour dates so far are:
1 - Birmingham NEC
3 - London Arena
7- Sheffield Arena
8 - Glasgow S.E.C.C.
12 - London Wembley Arena
14 - Newcastle Arena
15 - Manchester Evening News Arena
And there's an extra treat in store for Popstars fans. The Cheeky Girls will make special guest appearances at the shows.
