Are Secret Life's Shailene and Francia fighting?

Every Monday night, I'm glued to my television watching The Secret Life of the American Teenager. One of my favorite story lines is how Shailene's character Amy, and Francia's character, Adrian, can never get along they make it so believeable that they hate each other that it seems like they have beef in real life. So when I went ice skating with them in NYC, I became a super sleuth to find out if they really were frenemies. And I came to realize that nothing could be further from the truth- the two girls are BFFs! They even skated together on the ice! "Everyone in the cast gets along really well," Shailene told me.
