Ariana Grande scores first UK #1 with 'Problem' + makes history...

As if Ariana Grande's new single 'Problem' (featuring Iggy Azalea) couldn't get any bigger. It's only gone and topped the Official UK Singles Chart. She's also made history by being the first artist to have scored a #1 in the UK with the new chart system, which counts streaming as well as downloads and purchases. Congrats! People will probably use that to discredit her achievement but a #1 is a #1 at the end of the day.

Besides, it's not like the song hasn't impacted other territories in a major way. Unfortunately, she won't be partying with us for the celebration. She has cancelled her scheduled UK tour appearances to stay in Florida due to her grandfather being really ill in hospital. Sad times.
