'Love Me Harder' songstress Ariana Grande is due to kick off the first date of her Honeymoon tour tomorrow night and she has revealed that last minute preparations have left her feeling anxious. 

The jaunt will begin at the Independence Events Center in Independence, Missouri on February 25 and took to her official Twitter page this afternoon (February 24) to confess that she's feeling a mixture of exhaustion and excitement about the upcoming run:

"Already the longest day of my life. So much to get done still. Anxious/nervous/excited/exhausted/ready/not ready! tomorrow!!!!???! How did it come so soon??!?? We're gonna be up all day and night finalising this show for u. See u tomorrow Kansas city loves."

British pop-rock band Rixton have been confirmed to support Grande on the tour and they recently joked that they might prank her if they get the chance: "Every now and again, not too often. You tend to know what winds each other up. We don’t really prank each other. If we can sneak past security and get into her (Grande's) dressing room, then maybe!"
