Dianna Agron gleefully sexes up for Flaunt photo shoot

In a new Flaunt magazine spread, Dianna Agron rocks heavy makeup, lingerie and a Gaga-esque hat that are worlds away from Quinn Fabray, the prim (though sexually active) teenager she plays on FOX's "Glee."

Agron talks in the accompanying article about what it's like being part of the "Glee" phenom and her decision to chop off her blond locks in May.

"It's almost like putting on the glasses and all of a sudden you're smarter," said Agron, who sold her first screenplay before coming to Hollywood and recently directed a music video. "It's a very interesting and lovely observation that I keep having of how people treat me now that my hair's different."

And, despite some recent dischord from the "Glee" family and the punishing "Glee Live" concert schedule, the 25-year-old actress says she's the happiest she's ever been.

"Ever. High school, middle school -- I've loved every part of getting older and growing, but I definitely think that this is the most I've ever felt like myself and that I'm being treated like who I feel I am."
