'Dirty Diana' should be 'Glee' star Dianna Agron's new theme song, as the actress is showing off a dark and sexy hybrid of modern goth and old Hollywood glamour in her new spread for Flaunt magazine. If you've got it, flaunt it and that's exactly what the actress -- who plays Quinn on the hottest show on TV -- is doing.

For the mag's August issue, Agron shows off a completely different side of herself. With glossy, blood-red lips and blackened, smoky eye makeup, everything about Agron's spread is dramatic and vampy. But the art director never lets it cross over into campy.

Agron's bobbed hair is messy and textured, and could inspire plenty of long-haired ladies to head to their salon and ask their stylists to just chop it all off. It's pretty much a universal cosmetic "don't" to pair dark eyes and dark lips because it's too heavy and unbalanced, but few starlets can pull it off.  Agron, however, makes it work because she's that naturally beautiful. We love that she had the courage to go so dark in the Flaunt spread!

Most of Agron's outfits for the shoot are jewel-toned, and she looks utterly jaw-dropping in an emerald green bodysuit with over-the-elbow black leather gloves. She also looks gorgeous in a black sequined slip dress and will carve out a permanent spot in your cranium once you get a glance at her in that golden strapless dress with heels. Mmm hmm!
