The stunning Kate Bosworth is InStyle’s September issue cover girl and exclusively reveals all out her wedding plans, approaching 30 and relationships.

Looking utterly amazing on the shoot, Kate explains how she’s actually looking forward to leaving her twenties behind: 'There's not been one female I've spoken to who has told me their twenties were easy,' she says. 'Everyone  talks of how difficult your teens can be, but the rough and tumble of your twenties is a bit of a secret. In one sense it was a whole lot of fun but I felt confused and like I was going through growing pains a lot.'

Revealing all out past and present relationships, the actress also opens up about her fiancé director Michael Polish: 'I never even dated my husband-to-be. He said to me after just a few weeks, before we were even together, "I'm going to marry you." He just knew.'

As for her forthcoming nuptials, she confirms we will be seeing a wedding with a difference: 'I can give you one detail: it's not the norm and whisky will be involved.'
