Oh, she's just being Miley!
And by "being Miley" we mean licking her lips at her 20-year-old stud muffin boyfriend, Justin Gaston, as he blew kisses to her from the runway at the Christian Audigier fashion show.
That's not only inappropriate and tacky, that's straight up unprofessional!
Tyra would serve him up a Top Model lashing so fierce he'd think he'd just been hit with a cell phone.
Miley and her momager, Leticia, were both in attendance on Wednesday night, and a spy says that the 15-year-old and her boyfriend - 5 years her senior - were joined at the lips backstage. And someone said they overheard the couple planning various sordid after party activities, including a sleepover at Justin's place.
Her presence at the show, surrounded by a barrier of bodyguards, caused such a fuss that other celebs, such as Heidi Klum, went virtually unnoticed.
Come on! Even Lindsay was better behaved than that!
