Little Mix stop by the Waterstones shop for their “Our World” book signing in Bloomsbury, London, England on Saturday (October 22).
“Wow! We can’t believe that after only four days of sales we’ve managed to get to No.1! We can’t thank our fans enough! We’re over the moon! Our 4th No.1!” the group shared.
“Shout Out To My Ex” is the group’s fourth UK #1 single and ranks as only the third UK #1 single from a UK artist this year, right after James Arthur and Zayn Malik.
