Former Disney channel stars Demi Lovato, Miley Cyrus and Joe Jonas are celebrating 4/20, an unofficial holiday honoring marijuana culture, together on Lovato's Instagram.

Lovato shared an interesting photo collage Monday morning featuring herself with her colleagues. In the picture she and Cyrus both have halos over their heads with their arms together and Jonas' floating head is seemingly smoking a cartoon blunt.

Surrounding the stars are (appropriate) Mickey Mouse heads with peace signs inside, as well as two images of cartoon marijuana leaves.

"In honor of our former escapades, I thought you'd like this to remember your first blaze.. Happy #420 @joejonas. #disneyhighclassof09," Lovato captioned the picture.

Lovato was referring to the first time Jonas first smoked weed - which was due to the pressure of Cyrus and Lovato.

"I must have been 17 or 18," Jonas told Vulture in 2013. "They kept saying, 'Try it! Try it!' so I gave it a shot, and it was all right. I don't even smoke weed that often anymore."

Cyrus or Jonas have yet to comment on Lovato's picture, but Cyrus is celebrating 4/20 on her Instagram in her own way.
