Lady Gaga at V Fest

Katy Perry wasn’t the only American gracing London with her presence at V Fest yesterday — Lady Gaga was there too! If Gaga keeps up this touring/promo schedule, she’ll be well on her way to world domination by the end of the year. Trust.

Leave it to Lady Gaga to wear a modified disco ball onstage, but she somehow managed to pull it off. Her hair is pretty awesome, too.
