Heather Morris, the best female dancer on Gleeand a fan fave as the sweet, if intellectually challenged, Brittany, talks about fitness, and her boyfriend -- darn! -- in this month's Women's Health. The issue's timed to hit the stands Tuesday, coinciding with the show's season finale as New Directions takes a trip to New York for nationals.

Recently, Brit worried about cracking an egg in home ec: "This is really confusing because this is a chicken's house." Some of her best moments of confusion: She thought an anthem was the bottom of an ant's pants, a ballad was a male duck, and dolphins were gay sharks. Brittany would make a lousy Women's Health topic: "I don't brush my teeth. I rinse my mouth out with soda after I eat. I was pretty sure Dr. Pepper was a dentist."

But she has some personal insight: "Most teachers think that by cutting class, I might improve my grades."

Morris has a little more on the ball, and she displays it in the magazine interview, but she still has fun with her character: "The secret behind my fabulous legs? Eat a lot of goldfish."

The real secret: An insane amount of working out, which Morris seems to love. Something called "Piloxing," which is a combo of Pilates and boxing. Free weights. "Tons of squats." Something else called "Hot Yoga Sculpt," and who wouldn't want to watch her doing that? She says her boyfriend, high school honey Taylor Hubbell, whom she's been dating five years, loves to watch.

The article explains how Morris, one of Beyonce's backup dancers in the music video "Single Ladies," was hired to help the Glee kids with choreography on their version. She was so much fun, she got a small role, and she was so much fun after that, the writers kept giving her bigger and bigger parts.

Morris will Tweet live Tuesday night while the show is on (9 p.m. on Fox), from the Women's Health feed (@WomensHealthMag) with the hashtag #BrittanyOnGlee. And the magazine is offering some behind-the-scenes video of her photo shoot here.
