Why Are Justin Bieber And Selena Gomez Feuding With Ashley Benson?

Justin Bieber and Selena Gomez were total BFFs with Pretty Little Liars actress Ashley Benson, often double-dating with Ashley and her boyfriend, Justin's BFF swagger coach, Ryan Good. Selena and Ash were especially close, starring in the upcoming Spring Breakers together. So why are the Biebs and Sel feuding with Ashley? James Franco may be the culprit!

Apparently the Biebs and Selena are NOT pleased with AshBenzo's new relationship with the multitalented 34-year-old heartthrob, especially since Ash dumped Ryan to hook up with James. Yikes! 

An insider close to Selena reveals:

"After Emma Roberts turned down the role because she didn't want to gain weight for it, Ashley practically begged Selena to get her in front of producers for the part. She did, because she thought they were all friends, but it was clear early on that Ashley had something going on with James."

To make matters worse, the source alludes that Ash may not have called off her relationship with Ryan before getting with James. 

The source dishes: "Once the shoot wrapped, Ashley told Ryan they needed to 'slow down' and then booked a flight to New York City to go see James' art gallery showing. Selena is pissed off that she went out of her way to vouch for Ashley, only to have her dump Ryan."

The Biebs and Selena don't seem like two people you want on your bad side! 

Do you think Justin and Selena have a right to be upset with Ashley? If you were Ashley, who would you choose?
