On The Movie Bit
 

At the end of the jj2 movie spaz sees a girl that looks like Lori is that Lori or not im puzzled

Oringinaly Lori was that rabbit, but the creators (being the typical guys they were >:P) decided she wasn't sexy enough to sell more JJ2, so she was redone. However, when she was first anounced she was called the sister of Jazz and Spaz, so she lost her status as Spaz's girlfriend.

Aye, such is so. You can read that and more in the About Lori section of the site.
