Kate Winslet won't use Botox.

The 'Titanic' star has revealed she would instead prefer to let her wrinkles ''stay'' rather than try and get rid of them with injections.

She said: ''Well, it's definitely happening on the old face, that's for sure. The wrinkles are here and they're here to stay.''

The 39-year-old actress also feels as though she can now finally feel confident about her curvy figure.

She added to the new issue InStyle magazine: ''I still dip in and out of feeling confident as much as the next person, but I can genuinely say, now more than ever, that I really do love the fact that I'm curvy. I've got boobs and a bum and a man who loves me.

''When you go through the sort of scrutiny that I have, you have to choose a means of dealing with that level of judgment. My way has always been to take a good look at how my career is going. The way I see it, I have an incredibly fulfilling, rewarding career that has nothing to do with the size of my arse.''

Despite feeling at home in her own skin, Kate previously admitted she needed ''all the help'' she could get to stay looking young.

She said at the time: ''This (serum) is magic. I just bung it on every day under my moisturiser, or make-up, or whatever, and it really does make a difference. And I'm 39 next week, so I need all the bloody help I can get.''
