[Intro]
'Cause you're hot then you're cold
You're yes, then you're no
You're in, then you're out
You're up, then you're down

[Verse 1]
You change your mind like a girl changes clothes
Yeah, you PMS like a bitch
I would know
And you overthink, always speak cryptically
I should know that you're no good for me

[Chorus]
'Cause you're hot then you're cold
You're yes, then you're no
You're in, then you're out
You're up, then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up
(You) You don't really want to stay, no
(You) But you don't really want to go, oh
You're hot then you're cold
You're yes, then you're no
You're in, then you're out
You're up, then you're down

[Verse 2]
We used to be just like twins
So in sync
The same energy, now's a dead battery
Used to laugh 'bout nothing, now you're plain boring
I should know that you're not gonna change

[Chorus]
'Cause you're hot then you're cold
You're yes, then you're no
You're in, then you're out
You're up, then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up
(You) You don't really want to stay, no
(You) But you don't really want to go, oh
You're hot then you're cold
You're yes, then you're no
You're in, then you're out
You're up, then you're down

[Breakdown]
You're hot then you're cold
You're yes, then you're no
You're in, then you're out
You're up, then you're down

[Chorus]
'Cause you're hot then you're cold
You're yes, then you're no
You're in, then you're out
You're up, then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up
You're hot then you're cold
You're yes, then you're no
You're in, then you're out
You're up, then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up
(You) You don't really want to stay, no
(You) But you don't really want to go, oh
You're hot then you're cold
You're yes, then you're no
You're in, then you're out
You're up, then you're down

Katy Perry

Katheryn Elizabeth “Katy” Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter, businesswoman, philanthropist, and actress. She was born and raised in Santa Barbara, California. Having had very little exposure to mainstream pop music in her childhood, she pursued a career in gospel music as a teen and released her debut self-titled studio album in 2001. She also recorded a second solo album in 2005, (A) Katy Perry, which was scrapped.

Afterwards, Perry (her mother’s maiden name, taken to avert confusion with Kate Hudson) reinvented herself as a party girl pop star, breaking out with 2008’s One of the Boys and the #1 hits “I Kissed a Girl” and “Hot n Cold”.

Follow-up Teenage Dream (2010) equalled Michael Jackson’s record of five chart-toppers on the same album, and made Perry even more ubiquotous in the pop landscape. Following her marriage and eventual divorce from British comedian Russell Brand, she released an updated version, Teenage The Complete Confection and concert film Katy Part of Me in 2012. She released her fourth album, Prism, in 2013, along with some standalone singles, such as “Rise”.
