“Can’t believe it! Thank you so much to our lovely jubbly fans for getting us this just five days after release. To our team who have worked tirelessly on the #ShoutOutToMyEx campaign, especially this week to get the top spot! To my friends and family…after an awful week, something amazing has come out of it. And I do not know how I would ever cope without my sisters @jesymix14 @leigh_love_life @perrieeele ???? it doesn’t matter how shit things are, having these by my side always makes things a little better,” Jade reacted on Instagram.

She added, “This song is for anyone who’s had a bad break up and has come out better for it! ????????????#ShoutOutToMyEx. BRING ON THE GLORY DAYS.”
