The 'Something New' singer also spoke out about her burgeoning career as an actress, but admitted that music will always be her first love.
"We are still in rehearsals at the moment," Sarah revealed on This Morning today (4th February), regarding Girls Aloud's UK arena tour. "We've all kind of had our solo projects and interests that we wanted to pursue.
"But we've all come back and we've grown up a lot more, we're a little more diplomatic and have a lot more say," the girl band star explained.

Sarah also opened up about moving into acting with her role in the new British comedy Run For Your Wife, in which she stars alongside Danny Dyer and Denise Van Outen.

The UK trailer for Run For Your Wife was revealed several weeks ago and the film is out in UK cinemas on 14th February.
