Back in the fall, Spring Breakers star James Franco denied hooking up with his co-star Ashley Benson, but based on their hardcore PDA at the premiere after-party in Los Angeles last night (March 14), it looks like the jig is up. 

According to an insider at Hollywood Life, the cast mates are “1000 percent hooking up.” Apparently, once the cameras were off, Ashley and James were caught holding hands and were even spotted sneaking a kiss while Ashley sat on his lap. Scandalous!

Between all of the romance rumors over the past few months, the epic Justin Bieber parody video that they filmed together, and their recent red carpet canoodling, we’re getting a total boyfriend/girlfriend vibe from these two.

What do you think of the news? Could Ashley and James  just be having fun, or are they coupling off? Let us know your thoughts in the comments below!

Don't forget to check out HollywoodLife's full story and the super flirty photo they snapped of Ashley and James.
