Poor Kristen. How can one really blame her for feeling a little hurt when she heard rumours that one of her friends, Riley Keough, is now dating her ex-boyfriend, Robert Pattinson?

It bothered her so much, Kristen called Riley to hash it all out.

According to OK! Magazine, Kristen called Riley and said that she likes and respects her as a friend but she just does not think that it will ever be right to go after a good friend's ex who is suddenly single and available.

It seems that Kristen did not get what she wanted out of the conversation but she certainly got what she needed. OK! Magazine says that the girls had a civil and decent conversation.

When KStew told Riley that she didn't think it was cool to date a friend's ex-boyfriend, Riley answered that she was sorry that KStew felt that way. This isn't exactly an apology. But it is Riley acknowledging how Kristen feels about her rumoured relationship with Robert, even though she clearly has no plans to stop seeing Kristen's ex.

Many fans have commented that Kristen is overreacting. Robert and Kristen have parted ways and Robert is playing a fair game now. It's not like Riley was Kristen's BFF.

What's your Say? Should Kristen be upset at the idea of her ex-boyfriend dating her friend?
