Kate Hudson says shooting movies is like a holiday from parenthood

Kate Hudson says that shooting movies is like a holiday from parenthood.

The 'Raising Helen' actress - who has a four-year-old son with ex-husband Chris Robinson - realized how tiring raising a child can be while shooting her latest movie 'Fool's Gold' in Australia.

She said: "That was really hard as it was the first time I'd ever been away from Ryder.

"But it ended up being one of those things where I realized that you really do need time away from your children to remember you're a person, too!

"You know how it is - you try to sleep in, but even while you're sleep, you've always got one eye open and one ear open, too.

"So I end up exhausted. When it's only me, I can just go to work and come home."

Despite her much needed respite from Ryder, and her differences with ex-husband Chris, the Hollywood babe, 28, insists her son will always be her number one priority.

She said: "When Chris and I realized we were unhappy in our marriage, we said, 'Are we going to let our egos get in the way here? Or are we going to do the right thing for our child?'

"I would literally go to the end of the Earth for Ryder, and so would Chris. As far as we're concerned, he's the priority."
