Kate Hudson was ''boy crazy'' in her younger years.

The 38-year-old actress - who is in a relationship with Danny Fujikawa - has admitted that whilst she believes she was largely a ''very focused little girl'' who didn't rebel against her famous parents Goldie Hawn and Bill Hudson, she did have a phase during high school where she was obsessed with the opposite sex.

Speaking to Net-A-Porter's The Edit magazine, Kate said: ''I was a very focused little girl,. I didn't rebel from my parents because I wanted validation from them.

''I never came home with a piercing or a tattoo; I was always the designated driver. I got a bit boy-crazy in high school, but I didn't party, so I was never the coolest person in class.

''At the weekends, I wasn't chilling with friends; I had s**t to do! I still do - I can't not be busy.''

Meanwhile, although Kate - who has 13-year-old son Ryder with her ex Chris Robinson, and Bingham, six, from her past romance with Matt Bellamy - is no doubt happy to be out of her ''boy crazy'' phase, she recently admitted she isn't a fan of the ageing process.

She said: ''Ageing sucks. It's like a double-edged sword, because you accept that your body starts to change and gravity takes over and, as that's happening, you gain a sense of wisdom and get more comfortable with who you are ...

''I'm all for the creams and the lasers and longevity. I'm not going to lie: I'm one of those women who, if there's a filter, I'm using it. If someone said when would you have liked to have stopped ageing, it would have been about 29. You can use all the creams in the world but, I'm telling you, the best thing for ageing is being active and healthy, so I want to reach out to women about body positivity.''
