Hi, missyvixen52. As of right now, auditions for next season's "I Know My Kid's A Star" have not been announced. If the show is picked up for a second season, then most likely the auditions will be posted on the show's page on the VH1 website. They will probably require an audition video, but details will be provided when the auditions are announced.
However, I would urge you to seriously reconsider auditioning for this show before you go through with it. I am somewhat shocked that Danny Bonaduce is hosting the show, as he is the worst example of what can happen to a child star. The entertainment industry places an enormous amount of pressure on all actors, and children do not always handle this well.
Please make sure you are taking the best interest of your child to heart before entering them in a competitive television reality show.
