Not Reese & Robert's First Time!

This morning, production on Water For Elephants began in Filmore, CA and things might end up getting very awkward.
As you may have heard already, the period flick stars hunky Robert Pattinson alongside Reese Witherspoon. In Elephants, they will play lovers, but once upon a time, on the big screen, she played his MOTHER!
Travel back now to 2004, when Twilight wasn’t even a dream in Stephenie Meyers head and R-Patz was on NO ONE’s radar. Robert got a very small role in the flick Vanity Fair as Reese’s character’s son!
Weird!
Wonder how this prior relationship will affect some of the rumored “sexy affair” scenes ?!
