Brittany S. Pierce might not be the smartest Gleek at McKinley High (and that's putting it lightly), but don't be fooled  Heather Morris is one smart cookie! This gal has had four years of practice playing a ditzy cheerleader, but she says dumbing herself down for the part isn't as challenging as you might think.

"I think it's easy, she tells The Interview Feed. "I think it's just simple, especially, like, a lot of the directors are really good at just picking out what things mean, what the sincerity of it. So it helps when they're like, 'This is like that. This is as simple as like…when you're saying these words it's the feeling of this. It's a real emotion. You just have to portray it as it's real.'"

Heather does an amazing job balancing Brittney's ditziness with her emotional development, and the trick? To "just make it as sincere as you can." Heather opts for a deadpan delivery on most of her lines, but being super-sincere when she's saying such ridiculous things can be a challenge.

"Sometimes it's hard because if we're here for so long and I'm excited and I want to do different things, and they're like, 'No, you just have to say it. You just have to let it out.' I just have to be sincere and sometimes it's hard."

Heather's character is hardly one-dimensional, but we can see why she'd get frustrated by Brittney's non-stop ditziness. "There are just days when I just want to do something different because I'm just bored and wanting to do some random things, and they're like, 'No. You just have to be straight faced and you've just got to get it out,' and I'm like, 'Okay.'"

Yikes, looks like this gal is ready for a challenge! Is it just us or does Heather want Brittany to think outside the box?
