FarmVille's not the first Facebook game to go gaga for Gaga

When you log into FarmVille today, you'll be greeted with an explosion of Lady Gaga, well, everything. This new promotional tie in, designed to publicize Gaga's new 'Born this Way' album, includes a new series of quests, new crops, new animals (how bad do you want that unicorn?) and, starting today, exclusive access to the popstril's 'Marry the Night' song.

I have to point out though, that while this is the only Gaga-sanctioned debut in a social game, Playfish's Pet Society was actually the first to pay homage to the quirky singer, releasing a limited edition series of clothing and wigs (and, later, released a pic of a pet modeling Gaga's meat dress that she wore to the MTV Music Awards). A few players went so gaga over these accessories, that they created some, er, interesting videos of their decked out pets singing along to 'Telephone' and 'Bad Romance.' Peep them below.
