Hollywood Life Reports:

Ashley Greene had a very important date — to costume-shop at Halloween Express in Baton Rouge — and we know what she bought!

Ashley Greene did the Halloween shopping for herself and boyfriend Joe Jonas, and according to a source at Halloween Express in Baton Rouge, La., where she’s filming Breaking Dawn, she got over $500 worth of costumes.

We’re told she and Joe will have to make a choice — Alice in Wonderland-themed costumes (Alice and the Mad Hatter) or pirate-wear — as she purchased his-and-her outfits for both.

Even Ashley’s pooch is going to have its own costume choice, because Ash picked up two outfits for the pup.

Ashley arrived in Bogota, Colombia Oct. 27 to support her BF while on his tour in South America! We’re totally jealous, and bet she brought the costumes along!
