Talking to Cosmopolitan magazine this month, Kimberley revealed that not a lot had changed when the girls got back together.
She said: “It’s really nice. We’ve already fallen back into the same patterns; it’s weird. Well, Sarah’s not really a party animal anymore so that’s changed, but I still fulfill the same role.
“Like, on our first performance everyone was getting really nervous and I was thinking, ‘Right, OK, let’s try to calm this situation down.’ Cheryl’s quite motherly too, while Nicola and Nadine are the young ones.
“We’re still protective of them even though they’re women now!”

During the Girls Aloud reunion, Kimberley Walsh was also taking part in last year’s series of Strictly Come Dancing, making it all the way to the final and only just missing out on the title to Louis Smith.
With such a busy work schedule during this time, Kimberley admitted that she has always loved a challenge.
She said: “I love a challenge. If there’s something where I’m like, ‘I don’t know if I can do that,’ I’ll do it – just to prove I can. What can I say? I’m a glutton for punishment. I’m a bit psycho like that.”
With the strenuous rehearsal regimes that come with doing Strictly, Kimberley is now the proud owner of one seriously hot body.
Despite this, the singer finds it odd being described as ‘sexy’.
She admitted: “I find it hard to talk about myself being sexy, but I guess my shape is more womanly than the model look, and that’s sexier. I go with it; that’s how I am!
“But it’s not like putting on a dress suddenly makes you feel sexy. You need to feel good about yourself first. And I do – physically I’m really fit, and I’m really happy.”
And one part of Kimberley's body gained masses of attention during Strictly, her bum.
Kimberley Walsh joked: “It’s got a life of its own! Something about my bum was trending on Twitter recently and I was like, ‘Oh, my god, you lot are crazy!’ Nicola loves to give my bum a squeeze too. She’s very toned and a completely different shape so she’s like, ‘It’s a sponge!’”
We think that’s a compliment from Nicola but we’re not too sure.
The full interview appears in the February 2013 issue of Cosmopolitan, on sale 3rd January.
