When asked what their plans are for when The Big Reunion tour ends, Natasha said: 'We're definitely, definitely concentrating on the band. We've already got a record deal underway.'
She then added to the MailOnline: 'We are writing songs for our new album as well.'
Her interview comes as she also revealed on Twitter that she spent her Wednesday morning recording what they think could be their new comeback single.
The 30-year-old wrote: 'I'm off the studio to vocal @AtomicKOfficial potential come-back single!! Could today get anymore freakin' exciting!'
The comment caused lots of messages from lots of followers, to which she responded revealing they had plenty of material: 'Well, we have that many to choose from!;).'
As they were: On The Big Reunion they've been singing their old hits but Natasha has now revealed they have plenty of new songs they'll be bringing out
And it seems performing back on stage has given the singer the taste for continuing her pop career once more.
She said of the tour, which kicks off in May: 'Can not wait, it's quite intense though. It's every night for two and a half weeks.
'We're going to have to be well behaved. We won't be able to go to the bar, we'll have to rest our voices!
'We've had the best time. I'm not going to lie, going into it I was nervous because I thought what if we don't have the chemistry that we had when we were kids? But literally the first day back to work together was back to business and we all slotted back into our old funny ways... Loud and hyperactive.'
Natasha added: 'I mean, I just love working, working defines me. I love being a mum and being at home with my kids but I feel really inspired when I'm working and being on stage performing, doing what I love doing.'
Getting the taste for it: Natasha and her bandmates Liz McLarnon and Kerry Katona reunited for TV show the Big Reunion and are about to go on a tour in May
This week it was revealed that Atomic Kitten and the rest of the Big Reunion bands will also take part in the Big Reunion Christmas tour in December.
Natasha was speaking to the MailOnline as part of her bid to raise awareness for Macmillan Cancer Support.
Hamilton is helping to support Macmillan’s new fundraising event, 'A Really Good Night In', which will take place nationally on the evening of Friday 26 April.
Cancer has affected Natasha’s family ever since she can remember - her nannies, aunts, uncles, both mother and father-in-law have all been diagnosed with or died from cancer.
They're back: Hamilton revealed they'll still be concentrating on the band once the Big Reunion tour wraps up
And so she wants to do everything she can to raise funds and awareness to help beat cancer, including holding her own Really Good Night In with her friends.
She told the MailOnline about the campaign: 'Well, it's all about having a really good night in. We want everybody to get all your friends and their family around, either have a dinner party or a girlie pamper night or a poker night - or anything that just gets you to interact with your friends. And charge on the door or put a donation in the pot. It's just a new fun way of bringing awareness.
'As a young child my grandmother had throat cancer so that was many years of tough times.
'We have to be really careful, we have to have more checks. One in three people will end up with some form of cancer, it's a lot of people. And we need awareness and that's what Macmillan gives.'
New tunes: Natasha has admitted she's been thrilled with the response and getting back on stage
Speaking of her own Really Good Night In, she added: 'I'm going to have a dinner party. I'm going to cook a dinner, I've got my meal planned already, mozzarella and dried tomatoes and I'm going to have champagne and nice pedicures and manicures.
'I've been so busy with the girls and working so it will be a nice night for us all. It's just close family and friends this time. I wish I could invite my Big Reunion family but we all live miles away from each other. We should do another night and get them to donate as well.
The event focuses on close friendships and could include a variety of themes from a girly pamper night; a chance to get crafty and swap skills or simply drinks and nibbles, to help make sure no one goes through cancer alone.
