Katy Perry thinks her music video with boyfriend John Mayer is more authentic than Kanye West's "Bound 2."

The "Roar" hitmaker, who joined forces with John on the song "Who You Love," made the comparison about Kanye's latest music video which features his fiancee Kim Kardashian straddling him topless on a motorcycle.

"I thought our response was a little bit more authentic because my hair was blowing in the right direction," the 29-year-old singer joked, speaking on The Ellen DeGeneres Show.

The song appears on John's latest album Paradise Valley and Katy thinks their relationship works so well because they have a mutual appreciation for music. "Yeah we have a lot of fun. You know, we have music as an understanding and love between each other and we connect and you know it's like he understands what I do because he does the same thing. And so after a long day, if it's been tough, I don't really have to go into it, he just gets it. You know, so it's nice with that understanding," she continued.

The pop star, who split from her ex-husband, Russell Brand, in December 2011 after 14-months of marriage, describes her latest record Prism as being "a lot more vulnerable." She explained, "It shows another side of me and another layer of my mind and all the different things I've been through and the route of positivity I decided to take."
