Little Mix to perform at Grande's Manchester benefit concert

British girl group "Little Mix" is all set to perform at Ariana Grande's Manchester benefit concert tomorrow to pay tribute to the victims of the May 22 terror attack in the British city.
The band on Friday took to twitter to announce their performance at the gig.
"We are however, so honoured that @ArianaGrande has asked us to perform at the #OneLoveManchester show on Sunday," they posted.
The group had to cancel their performance on Britain Got Talent due to change of date.
"We were looking forward to performing #Power for you guys this Sunday on @BGT but following the date change we are unable to attend."

Besides Little Mix, singers like Justin Bieber, Coldplay, Katy Perry, Take That, Robbie Williams, Miley Cyrus, Pharrell Williams and Niall Horan will also perform at the concert.
