OMG!!! You heard it straight from Jennifer Aniston, anything is possible when it come to a 'Friends' reunion. Ellen asked Jenn if she would be open to it and she answers by saying she and the girls would be open to it, and so would the guys.
She also said anything is possible so I'm taking that as, there's an opening there.
For years many fans have wondered if it would ever happen and now finally it looks like Jenn is warming up to the idea. Lets cross our fingers for this one!
