Robbie added that her 29th birthday celebration was definitely one for the books. "It was a big 29th; I don't need a 30th," she said. By the look of her big smile in the photo, it's safe to say that Robbie's wig moment was one of the most memorable (and photogenic) parts of it all. It's also proof that, even with neon orange hair, Robbie still looks like the red-carpet queen she always is.
