The 'Superbass' hitmaker said she is feeling the pressure ahead of presenting the awards, which take place in Glasgow, reported Contactmusic.
"I was having a lot of anxiety yesterday actually because I know there is a lot of pressure and it's a big job and I always want to give my best and be amazing. After I rehearsed yesterday I felt a lot better - it's going to be a really, really fun show," she said.
Despite her worries, the 31-year-old singer said she will be the greatest EMA host ever.
