The Pussycat Dolls have admitted that they don't always get along.

Singer Nicole Scherzinger said the girl group argue but have also learned how to deal with the pressures of working with each other.

Speaking to the Metro, she said: "We are like sisters - we have our disagreements but most importantly we love each other and know how to be professional.

"We know how to stay out of each other's faces."

The band have recently been the subject of speculation about a split after their single 'Jai Ho!' was billed as the Pussycat Dolls featuring Nicole Scherzinger.
