You're nominated for The Truth About Love. So how does the magic happen?
When I start a record, I'm like, 'God, I wonder if I can even sing.' But I write poetry and keep a journal, then the first day I go into the studio, I'm like, 'Here we go, I'm turning the faucet on!' I bottle it up for so long that the inspiration is always there.
How'd you get Eminem to be on 'Here Comes the Weekend'?
He wanted me to be on his last record (2010's Recovery), so I said, 'Yeah, let's swap.' I'm a die-hard Eminem fan. I think he's awesome.
You vent about your husband, Carey Hart, in many songs. How does he feel about that?
He's like, 'Look, I know you, we have a good sense of humor, and I know what I signed up for. I only listen to half of what you say anyway!' When he starts listening to me too much, we have problems!
What does your 20-month-old daughter Willow think of mommy’s music?
The first time she heard my music, she kind of looked at me and got the weirdest expression on her face. I wondered, 'God, what's going on in there for her?'
Many people will be partying hard Grammy night, so what's your best hangover cure?
Drink a beer as soon as possible! I used to be able to drink a bottle of wine and not get a hangover. Now, after two glasses I have a headache.
The 55th annual Grammys will air Sunday, Feb. 10, on CBS at 8 p.m. ET/PT (7 p.m. CT) from the Staples Center in Los Angeles.
