They question has been raised: Are Ashley and Kristen like oil and water? Apparently, The night of Kristen's Birthday Bash Ashley was not in attendance. Was she not invited, or did she snub the event. Ashley has been known for saying things on the set are not like the Cullen gatherings, we fight we yell but at the end of the day we are sisters at heart. Is she referring to Kristen? I would love your take on this?
