Apparently fans of Jordin Sparks were upset that she is performing with both the Jonas Brothers and Honor Society and missing concerts to also perform with Britney Spears on her “Circus” tour and has reportedly missed some concerts due to illness.

Sparks sent out a Twitter message last night stating, “Guys please stop saying ur dissapointed in me 4 not being @ a show. Brit & Jonas @ THE SAME TIME isnt easy. I cant be everywhere @ once! :/”

She continued on to Tweet, “We have 2 juggle tour dates w/ stuff I've already confirmed. I'm not doing it because 'oh I just don't want to play there'..no way. I LOVE performing for you guys..you should know that. But things change and my schedule is ALWAYS changing. I just wanted 2 Get that off my chest bcs Ive been getting a lot of that this week & its irritating when I'm trying my best 2 keep up. Anyway, tonight Was amazing & such an experience I will never forget! I'm signing off now. Ottawa tomorrow!!! :) Goodnight twittlets! <3”

Jordin ended her Twitter night with the following statement to her fans, “Im still gonna keep working even if it kills me bcs its what I love to do. I hated not being able to perform those shows… i wasn't mad, just explaining why I wasn't at some shows and am at others. :)”

Sparks has been on tour in numerous cities performing almost every night since June 20th, opening for Britney and performing with The Jonas Brother’s. This past week Sparks announced she was ill, but still performing via Twitter, “Sinusitis! But my vocal cords are great, which is such a relief! Show 3/3 of the Circus tonight! :)”
