The Hills has been getting major flack this week for being a totally fake reality show. (Uh, you think?!)

First off, a bunch of Hills fans noticed that Lauren Conrad's hair and nail polished changed in this week's episode between her date and what was supposedly right after it. Also, Spencer Pratt and Heidi Montag were spotted filming staged arrival and departure scenes at LAX, but instead of going home to Colorado, Heidi just went to the bathroom to change outfits. (Oops!)

But the biggest faking centers around Lauren's 'tude. Spies for the New York Daily News were at the debut of the star's clothing line, and they say Lauren is so not the "sweetheart" you see on TV. "Lauren was in the booth and rolling her eyes the entire time she was there when the cameras weren't on," the spywitness says. "She was obnoxious to buyers as they were shopping in her booth and refused to say hello. But when the cameras turned on, Lauren immediately perked up and pretended to be interested." Whoa -- beeyatch to good girl in three seconds flat. That might be a new world record!
