Kate Winslet: 'I'm Not Calling My Son Rocknroll!'
Star denies that her new arrival will take her hubby's surname...
The Titanic actress told Glamour magazine that new son Bear will be taking her own surname - like her other two kids.
She said: "We haven't ever really had that conversation; it was always going to have my name. Mia and Joe have it as part of their name, so it would be weird if this baby didn't.
"Of course we're not going to call it Rocknroll. People might judge all they like, but I'm a f**king grown-up."
The plain-speaking 38-year-old also dismissed chat about losing her baby weight.
She said: "Having just had a baby, I'm not going to be thinking about my arse."
Kate has also voiced her opinion of Miley Cyrus this week.
