AND CHRISTMASSY. - THANK YOU.

YOU LOOK VERY DAPPER. - OH, THANK YOU VERY MUCH.

WE MAKE QUITE THE PAIR. - WE DO.

WE'RE BOTH COVER GIRLS NOW.

- OH, MY GOSH. WE ARE.

- YOU'RE A COVER GIRL.

- WE SHOULD JUST GO KNOCK ON PEOPLE'S DOORS

AND SING CAROLS AND GO, "WE'RE COVER GIRLS."

- OKAY.

I DIDN'T THINK WE HAD TO DO THAT AS COVER GIRLS,

BUT OKAY.

- IT'S THE FINE PRINT. - IT'S IN THE FINE PRINT?

- YEAH, IT IS.

[cheers and applause]

- BEAUTILESS.

- WE'RE IN A CLUB TOGETHER. I REALLY LIKE THAT.

- WE ARE IN A CLUB TOGETHER.

I LIKE YOU VERY MUCH. YOU KNOW THAT.

I THINK YOU'RE A TERRIFIC GAL.

I JUST THINK YOU'RE SO GREAT.

- THANKS SO MUCH.

- AND I'M SO HAPPY FOR--

THIS IS SO BEAUTIFUL.

THERE ARE SO MANY VERY PERSONAL AND RAW SONGS ON HERE,

AND YOU'RE NOMINATED FOR TWO GRAMMYS,

AND YOU COULDN'T BE MORE DESERVED.

- THANK YOU VERY MUCH. - CONGRATULATIONS.

[cheers and applause]

I LOOK FORWARD--

I LOOK FORWARD TO SEEING YOU AGAIN AT THE GRAMMYS.

LAST YEAR AT THE GRAMMYS, KATY AND I--

THERE'S ALWAYS PHOTOGRAPHERS RUNNING AROUND,

AND THEY WANTED TO GET A PICTURE,

AND I JUST DID AN IMPROMPTU THING

THAT GOT SO MUCH ATTENTION.

- YEAH. I DON'T KNOW WHY.

- THEY TO--WELL, BECAUSE YOU WERE WEARING

WHAT YOU WERE WEARING, AND HOW COULD I NOT?

- WELL? - WHAT AM I GONNA DO?

- THE OBVIOUS. - YEAH.

I DID IT RIGHT BEFORE THEY TOOK THE PICTURE,

AND IT GOT SO MUCH ATTENTION.

- I KNOW.

I MEAN, I JUST WAS...

I WAS JUST THERE TO BE CELEBRATING MUSIC.

- YES, YOU WERE.

AND I WAS JUST DOING THE SAME.

[laughter]

I WAS CELEBRATING MUSIC.

- WE REALLY ENJOY EACH OTHER.

- WE REALLY DO.

HOW IS JOHN?

- JOHN, HE'S GOOD.

YEAH, HE'S REALLY GOOD.

WE JUST WERE ABLE TO SING OUR SONG TOGETHER, "WHO YOU LOVE,"

AT THE LAST NIGHT OF HIS TOUR AT BARCLAYS IN NEW YORK,

IN BROOKLYN.

- LOVELY. I LOVE THAT SONG.

- THANK YOU. YEAH, I DO TOO.

- I LOVE IT VERY, VERY MUCH.

IT MUST BE FUN TO SING WITH SOMEBODY THAT YOU LOVE,

THAT YOU ACTUALLY CAN JUST--

'CAUSE A LOT OF PEOPLE SING IN THE HOUSE,

BUT THEY DON'T SOUND LIKE YOU TWO SINGING IN THE HOUSE.

- 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.

- AND ALSO YOU PROBABLY--

BECAUSE YOU USE YOUR VOICES SO MUCH,

YOU COME HOME AND YOU PROBABLY DON'T WANT TO TALK.

- WELL, SOMETIMES WE DO HAVE TO GO ON VOCAL REST,

BECAUSE, YOU KNOW, HE HAD A THING THAT HAPPENED

WITH HIS VOCAL CORDS,

AND HE HAD TO BE COMPLETELY SILENT.

LIKE, HE WAS JUST USING AN IPAD,

AND I REALLY UNDERSTOOD THAT.

IT WAS LIKE, I UNDERSTOOD THAT HE COULDN'T TALK,

AND THE ONLY WAY HE COULD TALK AND COMMUNICATE

WAS THROUGH AN IPAD.

BECAUSE SOME DAYS I HAVE TO GO ON COMPLETE VOCAL REST.

LIKE, NO ANYTHING.

NO WHISPERING.

WHISPERING IS ACTUALLY REALLY BAD.

SO THERE'S JUST A LOT OF SILENCE IN OUR HOUSE MOST OF THE TIME.

- THAT'S NICE.

OR YOU COULD PLAY PICTIONARY OR SOMETHING LIKE THAT,

'CAUSE THAT WOULD BE REALLY FUN.

- WE SHOULD JUST LEARN HOW TO SIGN LANGUAGE.

THAT WOULD BE HELPFUL.

- AND YOU'RE CELEBRATING CHRISTMAS TOGETHER?

- YEAH. - YEAH, THAT'S LOVELY.

NOW, AND YOU'VE BEEN TOGETHER HOW LONG?

ON OR OFF, LIKE, WELL, 15 YEARS, ON AND OFF, PROBABLY.

- YES. OLD SOULS.

- YEAH.

BUT IT SEEMS THAT YOU BOTH HAVE FOUND EACH OTHER,

AND YOU SEEM VERY, VERY HAPPY.

AND I GUESS IT TAKES A WHILE TO KIND OF FIND THAT RHYTHM.

- WELL, I THINK, YEAH, WHEN THERE'S TWO PEOPLE INVOLVED,

SOMEONE OTHER THAN YOURSELF,

YOU HAVE TO FIGURE OUT, YOU KNOW, A COMPROMISE

IN A GOOD WAY,

AND THERE'S A LOT OF RESPECT.

YOU KNOW, I REALLY ADORE HIM AND RESPECT HIM AS A MUSICIAN,

AND THAT'S WHY I WAS VERY EXCITED TO DO A SONG WITH HIM.

THE VIDEO--WE DID A VIDEO TOGETHER THAT IS REALLY FUN.

- I KNOW; I SAW THE VIDEO. I LOVE IT. I LOVE IT.

AND IT HAS A GREAT MESSAGE ABOUT FALLING OFF THE HORSE

OR THE BULL AND GETTING BACK UP.

- THAT'S RIGHT.

SOMETIMES IN RELATIONSHIPS,

YOU GET A LITTLE BUCK,

BUT YOU JUST GET RIGHT BACK ON.

- YOU GET RIGHT BACK ON.

AND YOU ARE NOW--

I'M SURE YOU KNOW THIS, BUT YOU ARE THE NUMBER ONE

TWITTERER.

I HAVE 48 MILLION FOLLOWERS.

[cheers and applause]

- YOU KNOW, I THINK PEOPLE LIKE FOLLOWING ME

BECAUSE THEY SEE THAT THERE'S AN AUTHENTICITY TO IT,

BECAUSE IT'S ALWAYS ME TWEETING;

IT'S ME SHARING ABOUT MY LIFE.

IT'S NOT ALWAYS ME JUST LIKE,

"BUY MY RECORD. BUY MY RECORD."

ALTHOUGH I DO SAY, "BUY MY RECORD," LIKE ONCE.

I SAY IT ONCE-- - AND THEY DID.

- BUT THEN, LIKE, I SHARE A YOUTUBE OF A CAT VIDEO,

AND THEY LIKE THAT.

- THERE'S NOTHING BETTER THAN THAT.

I SHARE A LOT OF CAT VIDEOS ALSO.

- I FOLLOW YOU ON TWITTER.

- I FOLLOW YOU. DO YOU...

- WE LIKE EACH OTHER A LOT. - DO YOU...

WE REALLY DO LIKE EACH OTHER A LOT.

DO YOU EVER MAKE THE MISTAKE

OF TWEETING SOMETHING OUT WHEN YOU HAVE HAD A COCKTAIL?

- UH, NO. I DO A LOT OF DRAFTS.

I USUALLY DON'T DRINK AND TWEET. THAT'S KIND OF MY RULE.

- IT'S DANGEROUS. - IT'S VERY, VERY DANGEROUS.

- LIKE, YOU WAKE UP IN THE MORNING;

YOU'RE HALF-DRAFTED.

- YEAH. I'M HALF--

YES, I THINK THAT'S-- A GOOD EXERCISE IS TO--

IF YOU FEEL LIKE--

ALSO, I HAVE A FEW PEOPLE THAT I'LL BE LIKE,

"DO YOU THINK I SHOULD SO THIS?"

AND THEN THEY'RE LIKE,

"WELL, YOU SHOULD SLEEP ON IT, PROBABLY."

AND I WAKE UP THE NEXT DAY, AND I'M LIKE,

"OH, YEAH, THAT WASN'T A GREAT IDEA.

NO, NO."

- YEAH.

IS JOHN ONE OF THE GUYS YOU ASK

IF YOU SHOULD DO IT?

- EVERY ONCE IN A WHILE, YEAH.

- DO YOU STOP HIM FROM DOING THINGS TOO?

- NO, HE'S ACTUALLY REALLY GOOD AT IT.

HE DOESN'T HAVE A TWITTER, BUT HE DOES AMAZING INSTAGRAMS.

I'M NOT AS GOOD OF AN ISTAGRAMMER,

BECAUSE I'M LIKE, "WHY SHOULD I RULE BOTH INSTAGRAM AND TWITTER?

LET SOMEONE ELSE RULE."

YOU KNOW?

- AREN'T YOU NICE? - NO, I'M SUPER NICE.

I JUST WANT ONE THING.

- THAT'S WHY WE LOVE YOU.

WE'LL TAKE A BREAK.

MORE WITH THE WONDERFUL AND GENEROUS KATY PERRY AFTER THIS.
