A source close to the situation explained:
Kristen Stewart is just a ball of emotions this week!
We're sure the script called for some crying, but we're wondering if she drew upon something in her personal life to bring on the waterworks!
Are they getting back together? Did Rob tell her he's not ready for a second round of romance with her? Or are they really just going to take the friend route?
We must know!!!
We hear Kristen only has a minor role in this new flick, including this dramatic scene that had her storming out of an NYC apartment. She was dressed to depress in a wool sweater, dark pants and shirt and a beanie over her unkempt hair.
Make sure to leave that wardrobe in your trailer, Krissy and do yourself up right for your next secret get-together with Rob!
