The girls have sadly gone quiet.

Girls Aloud, which is the most successful UK girl group of the 2000s, is splitting up for good, according to Huffington Post UK.

The five-piece female singing group had recently completed a successful comeback tour before taking to Twitter to announce the permanent split.

"Dear Alouders, we just want to say from the bottom of our hearts Thank you!!" the message reads. 

"Your love and support will stay with us forever but we have now come to the end of our incredible time together," the group continues to tell its fans. "Love you lots." 

The group formed in 2002 on the ITV show Popstars: The Rivals.

Girls Aloud has sold over 4.3 million copies of their singles, including "The Promise," which won a Brit Award for Best Single in 2009.

The group is also responsible for rocketing Cheryl Cole to fame. The Girls Aloud member has been a judge on the British version of The X Factor and briefly on the American version as well.

We'll miss you, Girls Aloud  and that's a promise!
