Ariana Grande explains the meaning behind her 'Thank U, Next' burn book in behind-the-scenes video

Ariana Grande has explained the upbeat meaning behind her “burn book” in the record-breaking music video for “Thank U, Next”.

The music video spoofs various teenage dramas, with the book being a reference to the movie Mean Girls.

The book is used by Rachel McAdams’s character Regina King and the Plastics write down mean comments about the other girls at their school.

However, Grande’s book has a nicer use, as she explains in the behind-the-scenes video for ”Thank U, Next”.

“We put all of our past experiences in here and we write really nice things about them because, honestly, each person we’ve shared a little part of our self with has contributed to the people we are today and to our growth,” she says.

“[They’ve] probably helped us practice certain activities and get better at certain things, including loving ourselves. So this is a thank you, next book, which is very different from the burn book – so legal, don’t come for me. It’s a thankful book. You should make one.” Watch below.

Grande’s music video – which also spoofs Legally Blonde, Bring It On and 13 Going On 30 – set a YouTube record, reaching one million views in less than 34 minutes – faster than any other video.
