TMZ reports that their pet miniature pig, Piggy Smallz is in Ariana's custody during this breakup.
Ariana was the one who originally bought the pet pig in the first place, so it makes sense that he stays in her possession... As for Pete, he has a cute tattoo in Piggy Smallz's honour to remember him by.
However, Pete is king of covering up awkward tattoos, so we guess that might be the next one off the list!
