Arnold Schwarzenegger once said, “Pot is not a drug” and now, it looks like Lady Gaga would agree. In fact, she might even consider it to be a form of apparel. Trust Gaga to be quirky, and of course, give fans her usual quota of weird. After stunning fans with her outrageous costumes like the bubbles outfit, the frog dress, the plastic dress and of course the meat dress, she has made news with her latest choice of costume once again.

The 26-year-old celebrated Halloween dressed (of all things) as a marijuana plant. The dress left little to the imagination as she concealed just a part of her breasts with what looked like a marijuana leaf. Gaga wore a long green skirt and a green wig. The singer also wore the leaf on her shoulders and on the side of her face.

The “Judas” singer wore a puffy sleeve-like thing on her elbows. She seemed very excited about her outfit and took to Twitter saying, “So i was weed for halloween. BEST COSTUME EVER ITS SO FUN. Princess High the Cannabis Queen.”

Gaga stuck to her trademark style of makeup, with dark winged eye-liner and bright red lips, except that she kept her makeup a tad bit simpler than she usually does. However outrageous and skimpy the dress might have been, one thing she made sure to show off was her weight loss.

The singer had been recently slammed for putting on quite a bit of weight, but now she seems to have lost oodles of it and it looked like she really enjoyed wearing the costume.

“She feels great. She did little things like not drinking coffee or caffeine. . . She doesn't care particularly too much what people think, but she knew she looked good the last few nights and wanted to show it off,” US Weekly quoted a source as saying.

Gaga partied with her makeup artist Tara Savelo, according to The Daily Mail.
