Lady Gaga is known everywhere, and no where is this more evident than in Zynga's FarmVille. The sheer scope of this media cross-promotion is driving some players bonkers, but for the most part, FarmVillers are excited and gobbling up Gaga goods from the Market. Currently, the best-selling GagaVille specials are the Gem Tree, Purple Ponytail (a horse), Giant Gem Tree, and Crystal Sheep and there's even more to come... GagaVille is scheduled to run until May 26, so we're expecting more quests, free music, items, prizes, and possible promo spillage across other Zynga games. We'll be keeping a close eye on developing news for the next 10 days, so check this guide if you don't want to miss out!
