Just because frontman Billie Joe Armstrong is laying low in rehab, it doesn't mean Green Day aren't somehow being productive. Yesterday, the band posted '¡Dos!' -- the second album from their '¡Uno!,' '¡Dos!' and '¡Tre!' trilogy -- online for streaming, and now, they're premiering the video for 'Stray Heart,' the disc's first single. 

The clip stars a Billie Joe lookalike with a stray heart -- literally. As in, he has a big hole in his chest, and his heart -- which has little arms and legs and likes to wander around and chain smoke -- spends most of the clip trying to evade the BJ doppelganger and dropping blood wherever he goes. The whole thing is quite creepy, to be honest.

Director Robert Schober (Metallica, My Chemical Romance) helmed the clip, which was shot last month in Los Angeles after Green Day announced an open casting call via their Idiot Club fan club. The band members weren't on set and don't appear in the video -- not surprising, considering Armstrong's current status -- but the wannabe Armstrong does just fine in the role.
