The Call My Name singer has told Digital Spy that there will be "a lot of rehearsals" before the arena shows start in February 2013.
Speaking to the website at Capital FM's Jingle Bell Ball, Chezza said: "It's taken us all this week just to rehearse for the Jingle Bell Ball, so I'm sure there is going to be a lot of rehearsals for the tour as well.
"I'm sure it's going to be spectacular."
The 29-year old then confirmed reports that she's putting her solo career on hold for the girlband, stating: "Girls Aloud is me, it's where I come from.
"I've had ten years of success. The fans of my [solo work] are Girls Aloud fans. Some of them were 7 at the time and now they're young women. I've got a lot to give back."
Girls Aloud will begin their comeback jaunt in Cheryl's native Newcastle at the Metro Arena on 21st February 2013.
The girls recently admitted that they are having to use lyric sheets in rehearsals ahead of their tour, as they keep forgetting the words to some of their biggest hits after three years apart.
In other related news, a spokesperson for Cole has dismissed reports claiming she's hoping to make a comeback as a judge on The X Factor, stating: "Cheryl has no plans to return."
