No Doubt album `will be finished in two months`

It will be their sixth album together, and their first for 10 years, but Stefani admitted that she does not like it when people point out that fact.

'A lot of stuff happened during that time period,' she told Rolling Stone. 'Marriages, babies and, for me, two records and two clothing lines. So if you really worked out the math, you'd be like, 'Wow, you guys are going fast.''

She devoted part of the band's time apart to releasing her solo albums Love. 'Angel. Music. Baby.' and The Sweet Escape, but insisted that that kind of music came 'from my girl side and theatrical side', whereas with No Doubt, she is 'heels off'.

The mother-of-two added that it felt great to be working and writing with the group again.

'I had gone on my tortured journey of working with outside songwriters,' she said. 'I would throw up if someone made me do that again.

'It's so exciting to have a record coming out.

'And we all want the same thing - for it to be modern and catchy and addictive. Once you make music that connects with people, it's like you taste blood - you can't go back.'
