'Move' hitmakers Little Mix performed their first ever headlining concert at London's famed O2 Arena last night and have been given a plaque by the venue to celebrate such a great career milestone. 

A tweet was shared by the venue earlier tonight (May 26) and it revealed that the girls were awarded a special plaque to commemorate the achievement:

"To celebrate their first ever headline show here, Little Mix were presented with a special award by the venue’s general manager Rebecca Kane."

The O2 Arena also posted a photograph of the happy moment, which can be seen above left. 

Blonde bombshell Perrie Edwards also shared a message about the Salute tour and told her followers on social networking site Twitter that it's nothing short of a dream come true: "I will never forget this experience! We are so lucky! Thank you mixers for making my dreams come true."
