The two met on set this past year for the upcoming movie Spring Breakers, and must have hit it off, since they were spotted out together just the other day.
According to Radar Online, Ashley landed the role for the new movie because of Selena in the first place, so Miss Gomez isn't too happy that Ash and James are hooking up.
A source told the site:
"Selena feels used and kind of punched in the face seeing as though she got Ashley the role and Ashley just used the opportunity to break her friend's heart."
"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."
Apparently Ryan was suspicious that something was going on once Ashley started having less and less time for him, putting Selena and Justin in an awkward position:
"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 pi**ed off that she went out of her way to vouch for Ashley, only to have her dump Ryan. She got the role and she got the man, but she lost a good friend."
Sounds like Ashley is a little bit of a heartbreaker!
