Adam Lambert and Allison Iraheta answered some of the fan’s questions to E!Online in the interview published today at their site.
Below are the Adam-parts.

M.V.: Adam, I would love to hear more about the soundtrack. When will we find out?
Adam Lambert: I still can’t say anything. It’s definitely happening, but it’s not my call to be the one making the announcement. Sorry!

Lesley: Allison and Adam, are you guys gonna do a duet together like you did on the show? You guys were amazing!
Adam Lambert: It would be fun, but we don’t know yet. It’s too soon.

Tina: How are the new albums coming along? What’s the latest?
Adam Lambert: We’re kind of looking at everything and kind of hanging on to as much as we can and choosing from there. If we’re feeling a song, we’ll record it. If we’re not feeling it, we don’t. We’re going to powerhouse it after the tour is over as far as getting songs recorded and writing some new material. We’ve made a nice big dent in the process, but I think the majority of it will be done afterward.

Lesley: Adam, is your album gonna have songs like “Whole Lotta Love,” “Cryin’,” “One” and “Born to be Wild”?
Adam Lambert: I don’t think that’s actually really going to happen. I think the record needs to be new material. I do know we recorded some [of the live material from tour] that will be available on iTunes as a special offer.

Laura: How do you stay healthy on tour?
Adam Lambert: I think the question is: Am I staying healthy on tour? I’m trying. I avoid a lot of the crap food. I have some vitamins I take. I have this stuff that’s green powder that you get at Whole Foods. It’s called Super Mineral Vida Green. And I’ve been, like, trying to take that every day in, like, a smoothie to get my vitamins and greens and nutrients and all that, and that kind of helps me feel better.

Katie: Adam, what shoe size do you wear?
Adam Lambert: It’s like an 11 and a half.

Katy May: Adam, what is your most painful rejection?
Adam Lambert: It was probably in the dating world. Going after people and really feeling like there isn’t anything there that’s being reciprocated. That hurts. That’s happened numerous times.

Jun: How do you manage to keep your voice from getting hoarse after such intense performances almost every single night?
Adam Lambert: It’s definitely a learning experience in trying to learn to pace yourself. I found out that I can’t do all the super, superhigh notes every night, or else they won’t be there the next night. I’m just trying to learn to pick and choose my moments to really wail.

Allison: Adam, how do you handle the groupies?
Adam Lambert: Every night is such a big event. You have tons of people who are superexcited and passionate, which feels incredible. But at some point, I can only give so much and have enough energy to go out the next day. It really is draining. I’m not complaining about it at all, but it really is. There’s a point where you’re like, “Wow, I’m exhausted right now. I just gave a show. I met like 200 people and took pictures with everybody. And now I’m out signing autographs and people are, like, screaming insanely.” It feels great, but yeah, it takes a chunk out of you.
