Lady Gaga arrives at Heathrow Airport in London (August 20th 2009)

Dressed up like a pants-less vampire, Stefani Germanotta, best known to us as Lady Gaga, brought out the fangs (and her butt cheeks) as she arrived at London’s Heathrow Airport in the UK early Thursday (Aug 20).

Having just wrapped up a concert in Israel, the pop star will be performing for the UK’s V Festival Saturday and Sunday before heading back to NYC in a couple of weeks to do the 2009 MTV Video Music Awards. In addition, her co-headlining tour with Kanye West kicks off in Buffalo, NY on October 4th and is expected to run through mid-December.
