Jessica spoke to reporters on Thursday about her experience on the show and her plans for the future.
Were you surprised by the result?
"Not at all! I literally thought... I believed that Phillip was going to win, not because I'm not good but he has such a big fanbase and he was so good. He's really an artist's artist. He sang so many different songs and every one he sang just sounded like him. He has what it takes, and I'm so proud of him and happy for him."
Do you feel relieved to be done with the competition now?
"I kind of am, but I'm going to miss everything - the people, the schedule, everything about the competition was great."
Do you think it really matters that you came in second?
"Not at all. Jennifer Hudson came in, like, seventh, and she's one of the biggest stars from Idol and I have so much respect for her. I think I'll still get out there and have a good career, and I can't wait."
What was it like to sing with Jennifer Holliday?
"It was so much fun. I was in the moment and so was she. We were making the most ridiculous faces, I know, but we were just singing from our hearts and putting ourselves into it."
What's the best advice you received throughout the competition?
"I got a lot of advice from different people this season, but something that I believe in and that people have continued to tell me is that, you know, keep hold of my dreams and I can achieve success if I work really hard for it."
Are there any songs that you really wanted to sing but didn't get to?
"I really want to sing a Prince song called 'How Come You Don't Call Me Anymore'. I love that song and I really wanted to sing it, but Prince hasn't really cleared any songs so we had to choose something else."
For your album, what sort of music can we expect from you?
"I want to do more urban R&B with a little bit of pop but not much. I want to have that soulful kind of side of me come out."
Singing Whitney Houston during the finale must have been strange. Were you intimidated by it?
"Most definitely. We actually pushed that a few hours before the show started so I didn't plan on it until then, I didn't know I would sing it. It was a shocking moment for me but I was excited because I love the song. I love Whitney Houston and I'm glad I got to pay tribute once again."
There were a few bad song choices that you realised after the fact throughout the competition. Can you talk about the process of picking them, and how much choice you had in general?
"They didn't give us many choices and even then, there were songs I had to make adjustments to. But on the other hand, now I have time and variety and choices. I can listen to songs and pick what I want so that I can make my real single something that reflects me more."
How much did being voted off the week that the judges used their save on you affect your confidence?
"It was very difficult. It did affect my confidence and made it much harder, but it wasn't a bad thing because I was pushing too hard and I wasn't being myself because I was focusing on it way too much. My confidence did go away for a little bit, but when we got to the point where we had to sing ones that the judges picked, we didn't have any say in it, so I just got on with it."
How difficult is it to be spending so much time away from your family, since you're so close to them?
"It's hard, it's difficult but I'm learning it. But I'm not only doing this for myself, I'm doing it for them so it's not like I'm not being there for them. I don't really have much time to go see them now, I'll get to go home for about three days, but I'll cherish every single second."
There hasn't been a female winner since Jordin Sparks several seasons ago. Can a female win this show?
"I have no idea. I think that the only reason I really would have wanted to win was to break that whole guy reign... But I'm so proud of Phillip, he's so talented."
