"Hi, I'm Katy Perry and today I'm going to be ranking my favourite CALTUBE videos and adding a little comment to each. Tune in to see some kickass videos, and of course, my own video "Disco Fling" at the very end!"

10. Anything

Tinashe just exudes so much sex appeal. She spend an entire day in a coal mine and walk out looking effortlessly sexy. I can’t get my eyes off her in this video. I think the entire setting is so vivid and fun I wish I was there with her to be honest!

9. It All Comes Back To This

Honestly this is breath-taking. When you’re watching this, you’re so focused and on edge. I love it that Shawn is using his platform to raise awareness about these issues. It’s what we need. I’ve heard that this was a great collaborative effort between Shawn and the people of that town, so Kudos to Shawn!

8. Lemon

I was so surprised to see a steapmunk like video in this age, and frankly, I live for it! Troian is a breath of fresh air for the industry. I love the dark undertones of this video, they’re so interesting! Girl just do what you’re doing cause you’re doing amazing!

7. All Night

Zara my girl! I absolutely adore the colour changes in this video, they’re so fun. I’m a huge fan of quirky videos if you couldn’t tell (laughs). I love the “Bad Boys get nothing” line, it’s captured so well! We need more fun dance-y videos!!

6. Boy

There’s nothing that I love more than girl power! Boy makes me feel like such a bad-ass, I love all the girlies in it. Ugh I just want to go home and burn all the pictures of the men in my life (laughs.) Don’t gives us part 2 Camila, just make a full length movie!!

5. Rosa

Rosa is an incredibly brave music video, but would anyone expect any less from miss Lana Del Rey? I got chills when I first watched it. It depicts such a pressing issue for women in such a tasteful way. So much could have gone wrong in this video, but it didn’t. Truly a testament to Lana’s creative power.

4. In The Night

You’d probably think I’m crazy if I didn’t put this high on my list and you would be right! I absolutely love Kelly Clarkson and the 80’s inspired video just had me SO excited!! The storyline concept is so interesting and I am so curious as to how it’ll play out. More please!!

3. Betrayed

I love Mariah Carey. This music video surprised me so much, it’s such a departure from her other videos! The cinematography is STUNNING and the storyline is so hauntingly beautiful. Mariah is a phenomenal story-teller.

2. Put Me First

Oh look that face looks familiar? Who could that possible be? She looks a little bit like me I think. Ariana really served in this video. It’s such a fine appreciation of the human form. What a queen. We had a blast recording this with Tinashe & Belinda. Ariana is such a sweetheart!

1. Better Off Without You

How could I not make this video #1? Really raised the bar for music videos. Christina is a phenomenal actress, like everything about this short film is perfect. Of course we’re only playing the shortened version which doesn’t do the whole thing justice, but it’s spectacular nonetheless!

Up next is Katy's "Disco Fling!"
