This bag looks similar. I am no expert so I cant say if its the same. I'm some of the gucci experts can chime in.
That may be a vintage gucci that LiLo is carrying, but i could be wrong. You can also ask in the http://forum.purseblog.com/gucci/name-that-gucci-70014.html thread, and the experts are more than willing to help you out. Good Luck!! Oh and you could try doing a search on eBay. It's gucci signature boston style.
