Glee Gal Dianna Agron's Supersexy Spread

"I'm the happiest that I've ever been," the 25-year-old actress confesses in the new issue of Flaunt magazine.

Inside the mag, Agron shows off her rocking bod in a vampy black silk and lace sequined Dolce & Gabbana bodysuit and black tights.

In another shot, she gets high fashion, striking sultry poses in a yellow flapper-inspired Bottega Veneta corset dress, Brian Atwood pumps and bold red lipstick.

As for her much-buzzed-about newly chopped locks, Agron says, "It's almost like putting on the glasses and all of a sudden you're smarter. It's a very interesting and lovely observation that I keep having of how people treat me now that my hair's different."
