Lady Gaga is on her grind these days, barely having a spare moment for Ellen DeGeneres to wish her a happy 25th birthday before getting back to work on Born This Way. So instead of a night off to party it up at the Cheesecake Factory, the “Government Hooker” spent her birthday rocking the Staples Center stage. But Los Angeles fans made sure that last night’s show was a special one for Stefani, as the crowd of thousands joined in singing of “Happy Birthday”. Who better to celebrate with Gaga on her B-day, than an arena full of Little Monsters.
