Robin Williams' daughter has got a hummingbird tattoo in memory of her late father.

Explaining the meaning of the tattoo, she said: "If you've seen them fly, and if you know a little bit about them, they're impossible to keep in one place. Every time people see them it's not like they say, 'Oh my God, a hawk!'

"It's a hummingbird, and that was the reaction that my father got, from children, from fans, from senior citizens, and that's what hummingbirds always meant to me."

Meanwhile, Zelda insisted that she finds it "easy" remembering her father because he is "impossible to forget".

Making a rare red carpet appearance in Beverly Hills, she told People

magazine: "For me it's easy to continue remembering someone that is impossible to forget."

When asked about stepping back into the spotlight, she added: "It's not difficult, it's just a strange feeling. It's okay, it's going to be okay, but it is a transition.

"It's acknowledging that you have to stop feeling that the outside world does not exist, because for a short while it doesn't."
