Last year at this time, it was Britney who was enjoying some panty-free nights with Paris Hilton ... now it's Avril?
TMZ caught the wannabe punk last night at Hyde, Goa and Villa, where she exclaimed, "I have no underwear on!" and then we spotted her later -- chatting with Paris in the back of an SUV.
Avril at least kept what little dignity she has -- by not actually flashing the goods.
