The Hills, Season 4: There's a New Montag in Town

Come August, we'll be seeing some new faces on The Hills, starting with -- SURPRISE! -- Holly Montag, Heidi's older sister.

Um, really? Did everyone but me know this girl even existed? According to Us Weekly, Holly actually co-habitated with Heidi and LC during the second season of The Hills, but never got any air time.

Well, apparently the leprosy surgery went well and she's finally camera ready (though it's nearly impossible to find a pic of her online, hence the Heidi supertwins above).

So far, all we've learned about Holly is that she's 24 years old and started work in May as the assistant to Girls Gone Wild head honcho/ex-prison inmate, Joe Francis. Um, really? How has this info all gone under the radar for so long?!

Heidi Montag has a sister! Double the pleasure, double the fun.
