The Twilight heartthrob posed next to his super-sexy co-star Reese Witherspoon at the premiere of their new movie Water For Elephants. Reese was dressed in a gorgeous royal blue dress with a cleavage-baring cut, while R-Pattz showed up in a perfectly fitted all black suit.

The onscreen couple has become quite good at posing together, appearing together at a slew of premieres.  

 On Monday, the two were snapped at the Barcelona, Spain screening of the film and prior to that, Paris, France!

Meanwhile back in the states, Water For Elephants came in at No. 4 at the weekend box office, pulling in another $9.1 million. As of late, the film has grossed well over $32 million.
