7. Jess Glynne
While Jess hasn't been around as long as some of our other Summertime Ball-ers, she's truly transformed as an artist since 2014's 'Rather Be'. Jess has been fearless experimenting with her fashion, makeup and hairstyles in the last 2 years, so we can't wait to see how she'll wow us at Wembley this weekend! (Pics: PA Photos)
