Reporter for Tabloids??

Right now I am a Junior in high school and taking my second year of Journalism. I am wanting to become a journalist for a tabloid magazine. Preferably People magazine.. I need to know what are the "must haves" before I will be able to be a reporter for a tabloid.. Like what college should I go to? Like the best college, right now I am in Illinois but willing to move.. How many years of college? Stuff like that..
