Katy Perry Praises 'Good' Fiance
Katy Perry has been drinking less since meeting Russell Brand.
The 'California Gurls' singer - who got engaged to the British comedian in December after a whirlwind romance - still likes to go out and party with her friends occasionally, but her fiance's sobriety has had a "good influence" on her.
She said: "I still love to go out with my friends and I still like Pinot Grigio. But I've learnt from some of my hangovers and I don't drink as much as I used to. My last big night out was probably the Coachella festival.
"I'm happy that Russell is sober because it's had a good influence on me. It steers me in a more positive direction."
Although reformed womaniser Russell - who has overcome drug addiction and alcoholism - has had a positive effect on Katy, she isn't responsible for taming him.
She added to the UK edition of Glamour magazine: "It's not about taming. He changed for himself. Everyone knows no one will change unless they want to change themselves. It was a cosmic collision.
"We work together well in the relationship because there's no arguing. It's important to have your communication on the same level."
