For Halloween: Miley's BF Justin Gaston is her ex-BF, Nick Jonas

Miley Cyrus' new boyfriend Justin Gaston is really loving his moment of glory.  For Halloween, the former underwear model dressed up as Miley's ex-boyfriend Nick Jonas - and felt clever for possibly the fist time ever.

Apparently desperate to use feel close to Miley while she's overseas, Justin showed up at her Toluca Lake home, where he passed out candy like a good Christian lad. 

The most nauseating adorable part is that Sam Hancock, the boyfriend of Miley's stepsister Brandi Cyrus, dressed up too - like Kevin Jonas.  And then the tween wannabes gave an impromptu concert for all the cameras kiddies.  Isn't that special?  The only thing missing was Miley's bff Mandy Jiroux's boyfriend dressed up as Joe Jonas.  Maybe next year...
