See the mirror? I just thought MTV used it as a representation of Kristen's next project, "Snow White And The Huntsman". 

And with Taylor's promo, "You're not going anywhere, Taylor Lautner!", Taylor being 'abducted' by the cabbie represents his new film "Abduction".
 
But I think the most important question of all is, "Where is Rob's MMA promo?!" His should have been out now by this time, right?
