Ya Never know 
Lady Gaga 's Halloween costume left little to the imagination, which isn't too surprising given her flair for theatrics. What was surprising, however, is how quickly the pop star was able to slim down after gaining " 25 pounds " in mid-September.
To celebrate the holiday, the 26-year-old created her own ensemble. "I was weed for Halloween," Gaga tweeted Nov. 1. "Best costume ever! It's so fun. Princess High the Cannabis Queen."
