First up on "The "Gma heat index."" miss Indiana may not have won the miss usa contest but she was all the buzz, setting Twitter on fire. Sparking a conversation about body image. And ABC's juju Chang has her story. Nevada. Reporter: Miss Nevada may have won the crown at the miss usa pageant on Sunday. But it was miss Indiana, mekayla Diehl, who stole the show. Rather, her curvy figure stole the show. There she is, the buxom brunette, confidently strutting her stuff in stilettos and a tiny bikini. The internet responding with a flood of flattery. Since Sunday, there's been 10,000 tweets. One person tweeting, finally, a contestant that's not a bag of bones. And another writing, dear miss Indiana, thank you for looking like an average woman. Were you surprised at all by the Twitter reaction that you got? I was blown away. Never in my right mind would I imagine this would blow up to what it is. Reporter: Just how Normal is the beauty queen's body? While she may not be supermodel skinny, she is certainly thin. Diehl is 5'8" and wears a size 4. While the average American woman is 5'3 ifth'and wears a size 12 to 14. Is it a little back handed compliment? You're being called Normal when Normal in this country is quite a different size than what you are. I didn't take it as a backhanded compliment at all. I wasn't being called fat. I wasn't being called out of shape or ugly. In this regard, Normal is a good thing. Reporter: Diehl, even getting emotional talking about this experience. I never imagined to be competing in miss usa would do this. And it's so warming. It warms my heart to know that I can just by 30 seconds on stage, has touched so many girls' lives and boys, as well. Reporter: The self-proclaimed tomboy who played volleyball and ran track and field, said she didn't go overboard preparing for the pageant. I didn't starve myself or go to crazy extremes to get ready for the pageant. I lived a healthy lifestyle and trained just a little harder, like an athlete, to get ready for it. Reporter: What's the message to young girls who aspire to be miss usa someday? You can't worry about the girl standing next to you because you'll never be that girl. Your body is a gift. And you have to love it and have that confidence because that's the only thing you can do. You can't worry about being somebody else. You have to be yourself. Reporter: For "Good morning America," juju Chang, ABC news, New York. There's a message there. I like what she said at the end. It's true. We're so concerned about the person next to us and how they look, comparing ourselves to them. But to see that real emotion, and know she made a difference for the 30 seconds she was there on the stage, whatever that is. Wow. And we played it a lot more than 30 seconds since. It's going out and out. Thank you.
