The 29-year-old, who first found fame as a youngster on the Mickey Mouse club, said that new talent keeps her on her toes.
'I think it's great to have a little competition because I feel it inspires us [Team Britney] and makes us want to do better,' she told Stylist magazine.
'There are so many soulful singers, even the ones coming from London, like Adele and Jessie J, who are just amazing. It feels like a really cool time to be making music now.'
She continued, 'In the beginning obviously I was very young and I didn't know the ins and outs of things. I was very instinctive in what I wanted to do, and I was very vocal with my input on things.
'I think as the years have gone by, and as I've evolved as an artist, I've put even more into my career, and after that amount of time you start to know exactly what you want.'
