The “Heart Attack” singer Tweeted a pic of herself stretched out on a sofa — snoozing while getting her nails done for the event. “Just took an hour nap and woke up with THE BEST nails!!!! Hahaha,” she wrote.

The 20-year-old, who won the International Video of the Year award (which she said she’s going to put on her bookshelf) showed off her perfect nails — black with gold polka dots — while performing her hit in an all-black outfit topped with a leather jacket with cut-out sleeves.
