The initial start of the relationship between Aitken and Robbie was first reported in February, but allegedly ended when the film wrapped and Robbie left New Zealand to return to Hollywood. It's still unclear if the two are once again an item.

In Z For Zachariah, Robbie plays a teenager who survives a nuclear war. She can also be seen in Tarzan, where the actress will play Jane Porter. True Blood star Alexander Skarsgard is rumored to be the frontrunner for the leading role.
