Bindi Irwin celebrated her tenth birthday at the Australia Zoo earlier today with mom Terri Irwin and brother Bob, 4 ½. Wearing a sweatshirt from her clothing line, Bindi blew out the candles — decorated with an image of herself as a baby with Terri and late dad Steve Irwin — and then cut the cake. She recently told the Courier-Mail, "Double digits means double the fun which is so exciting."
