" Seventeen: Let&amp;#039;s talk about America&amp;#039;s Got Talent! What was the audition process like? Ali Christensen: We auditioned on a whim and we actually auditioned separately, but the judges wanted us to be a sister act. They wanted to hear us sing together, except we had never sang together before, except one time. So we went in the hall and threw a few things together and we kind of went from there!  17: And you obviously made it on! Was the process of performing on TV totally nerve-wracking? Christina Christensen: For sure! It was way scary. When you&amp;#039;re nervous, you can&amp;#039;t really sing your best and it was really intimidating because the judges were right in front of you and all of America was watching. 17: What are some of the doors that have opened for you since being on the show? AC: We&amp;#039;ve had so many amazing opportunities. Our favorite opportunity that we&amp;#039;ve had is the song that we are promoting, &amp;quot;Something About Me&amp;quot;. One of our very favorite judges on the show, Piers Morgan, was so sweet and would always say &amp;#039;there&amp;#039;s just something about you girls&amp;#039;, so we took that to heart and wrote the song. It tells people that no matter what they face in their lives that there is something about them. There&amp;#039;s something more to them than just the obstacles they face. 17: I think that&amp;#039;s something everyone can relate to because everyone goes through hard times. Where do you draw your strength from? AC: I definitely find strength in my sister, Christina. We draw from each other&amp;#039;s strengths. All four of our siblings have cystic fibrosis and it&amp;#039;s amazing to see the things they can do, despite their illness. We just want to give that message to everyone. Our obstacle is specifically having cystic fibrosis, but we each have challenges. 17: Having cystic fibrosis, what are some of the things you struggle with more than other teens?  AC: For me personally, I get really worn out and really tired throughout the day. It&amp;#039;s a struggle sometimes to remember all the medicine I have to take. Every time I eat, I have to take pills and I often have to undergo treatments. It&amp;#039;s a lot of time and hard work. CC: I always have a lot of treatments to do and I like to hang out with my friends which is hard when I have treatments. 17: What are some of the other songs you&amp;#039;re writing for your album about?  AC: The songs are so fun! There are some with really good messages and some are very upbeat.
