Just to clarify some rumours.
1. the cheating rumour (the most stupid thing I ever heard)
The articles can be divided to two types, cheating with Kristen Stewart or Riley Keough.
The topic looked serious.
But the articles are mainly about Jen’s interview from June issue of Marie Claire.
The “Riley” articles started from Page Six report.
In the original article, it just mentioned Nick sitting together with Riley and other friends.
Charl Brown’s response
Nick and Riley are only good friend.
Moreover, she has a boyfriend that has worked for Mad Max and Catching Fire.
2. Josh Hutcherson and Jen sighting.
The rumour probably started from this fanpic.
"Just Katniss and Peeta hanging out together"
Since the girl doesn’t reply, some fans think she saw Jen and Josh.
But according to another fanpic from the same place, Josh was clearly with another girl that’s not Jen. I am not saying that’s his girlfriend Claudia, maybe just his friend Heather or whatever.
