Rose Byrne found it "pretty hard" when she first moved to Los Angeles.

The 35-year-old Australian actress struggled to settle in the Californian city, finding herself getting homesick.
She said: "LA's not for everyone; I found it pretty hard, I was very homesick.
"I enjoy it more now - there's an incredible art scene there these days."
Rose then moved to London at the age of 25 for two years and says she particularly enjoyed returning to the English capital whilst filming her new movie 'Spy'.
She added: "When I was there it was becoming gentrified, but now it's in a different league. Broadway Market is so fashionable and intense now - it's like a catwalk ...
"There's a wildness about [London], it's more underground. The art and music and fashion that comes out of London is the most interesting in the world. New York can be a little mainstream."
Rose and her partner of three years Bobby Cannavale now live in New York together and the 'Bridesmaids' star credits the actor for helping her feel settled despite being far away from her "emotional home" of Australia.
She shared to Stella magazine: "Australia is my emotional home, and always will be, I think, but New York is where all my stuff is ...
"There's always a small part of me that feels like a foreigner in a foreign land, that this isn't my country and these are not my countrymen and I will probably return home one day; even if it's totally not true, it's a little story I have always told myself. But once you have a life here with somebody, that's obviously a total game changer."
