Robert Pattinson and Reese Witherspoon, in Zac Posen, reunited with a pachyderm this afternoon at the Sydney photo call for Water For Elephants, and this evening the two stars got even fancier to attend the Australian premiere. Members of the press were happy to see the two stars, and even made Rob smile by wishing him an early birthday! His actual big day is one week away, as he turns 25 on May 13. Reese and Rob touched down in the country just yesterday and had one night to acclimate to the big time difference after spending much of last week on the other side of the world — they also showed off the movie in France, Spain, Germany, and Rob's native Britain. Despite any jet lag, Reese was chipper first thing this morning when she took advantage of her downtime to shop around the city. She also engaged in some retail therapy while in Paris, but Rob hasn't ventured out much publicly. He doesn't have to worry about dog-walking duty while traveling, as his lady friend Kristen Stewart is watching his dog, Bear, back in the US.
