Despite the downsides of aging, Kate Winslet is very much looking forward to turning the big 4-0 on October 5 of this year.

'I'm definitely going to get to my birthday and feel I've earned it!' the gorgeous Oscar winner told People.

'I have the kind of wrinkles that are here to stay now. You know, not just the ones where you wake up in the morning and you go, "Oh that will go away in two hours' time." No, they're there. That's the way it is.'

The Berkshire-born blonde beamed over how well her three children - Mia, 14, Joe, 11, and Bear, 15 months - from three marriages all get along.

'They're absolutely adorable together,' the A Little Chaos actress said of her blended family.

'They're very helpful, I must say. I really love hanging out with my kids. They're terrific people. They're kind of happy in who they are, too, and that's all you can really hope for them - that they love being themselves.'

Kate continued: 'We've all got our health and we all laugh a lot. In my personal life, I really can't say why, but I've never felt more confident and happy.'

'[He] is so incredibly supportive that makes it possible for me to have those experiences,' the three-time Golden Globe winner smiled. 'I've got a really wonderful little family.'

Her daughter Mia's father is Extraordinary Rendition director Jim Threapleton, whom she divorced in 2001 following a three-year marriage.

That same year, Kate met Joe's father Oscar-winning director Sam Mendes and the couple divorced in 2011 following a seven-year marriage.

Ned works for the space-travel division of his billionaire uncle Richard Branson's company Virgin Galactic.

Having children so young, Winslet missed out on those formative college years, and she seems to hold a tinge of regret.

'I'm curious what that might have been like...just for a week,' the twice-divorced star laughed.
