Many people predicted that Ariana Grande would one day be a huge star and she is now a music chart topper and a popular actress. The young star said that it seemed like she became famous overnight and in reality, it did happen pretty fast.

Just a year ago Grande was excited to have a spot during the VMAs preshow. This Sunday she will host the event. That’s a pretty big jump in just a year.

Grande said that she is beyond excited to host the event and feels like it is almost unbelievable.

“To go from performing on the pre-show last year to opening the VMAs this year is utterly insane—and just too crazy to process,” Grande, said.

“And I feel like I won’t actually process it until after it happens, and then I’ll process it as I’m watching it, and then I’ll be l like…[whoa] OK, that happened.”

Grande said that she is very proud of the album and excited to share it with her fans. One of her favorite songs on My Everything is a ballad that was written for her by One Direction member Harry Styles.

The song, A Little Bit of Your Heart, is special to Grande and she said that it also shows off Harry’s talent as a writer.

“I think people know Harry, of course, first and foremost as a singer, but I think they’ll be very impressed when they hear his writing skills,” she said.
