Miley probably won the race of the most festive 4/20 pics. She may be on a break with her boyfriend Patrick Schwarzenegger, 21, but that can’t stop and won’t stop her from celebrating 4/20! The singer posted some shocking pics of herself with nipple pasties next to a bong, and got festive in other pics donning a marijuana leaf sticker on her face. Get it, girl!

Demi Lovato Smokes Weed With Miley Cyrus & Joe Jonas On 4/20

Testing out her collage-making skills a la Miley, Demi Lovato, 22, put this masterpiece of an Instagram together, honoring the time she got high with Miss Cyrus and their buddy, Joe Jonas, 25.

As Joe told Vulture, “I must have been 17 or 18. They kept saying, ‘Try it! Try it!’ so I gave it a shot, and it was all right.”

Ugh. Peer pressure, man.

In honor of our former escapades, I thought you'd like this to remember your first blaze.. Happy #420 @joejonas. #disneyhighclassof09✌️👽😈💰💚😝
