Robert Pattinson and Reese Witherspoon were together early this morning when they touched down at the airport in Sydney. They duo are working hard on the latest leg of their international press tour on behalf of Water For Elephants, and they're expected at another premiere and more interviews over the next day or so. The jet-setting costars have already made cameos in France, Germany, Spain, and Robert's British homeland. Between screenings and photo ops, they've had time for a little fun — they unwound earlier this week at an afterparty in London and even managed to enjoy some beer during an appearance on The Graham Norton Show. Reese and Rob, who are both in the running to be number one in our PopSugar 100 Favorite Stars of All Time category, missed a lavish night back in America this week when they skipped the Met Ball. Rob's real life leading lady, Kristen Stewart, did attend the NYC bash. A stay in the Big Apple was evidently in the cards for her, as Kristen Stewart was spotted with Rob's rescue dog, Bear, just yesterday.
