Ashley Tisdale Channels Lady Gaga & Leaves Her Pants At Home!

We're not entirely sure about this no-pants trend... Lady Gaga pretty much has free reign to do just about anything con su ropa sin sorprendernos, pero Ashley Tisdale?  La joven cantante just performed on the Los Premios MTV 2009 stage looking all kinds of sexy and wearing nothing but a nightie and hot shorts.  Qué crees?  Do you think she's copying Lady Gaga's steeze?

As for Lady Gaga, the avantgarde pop princesa took home dos lenguas: one for 'Mejor Artista Nuevo Internacional' y también por 'Canción del Año' para "Poker Face."

Make sure to catch all the moments you missed this weekend when Los Premios MTV 2009 re-airs on Saturday 10/17 at 2pm and 8pm, only on MTV Tr3s!
