The X Factor won't officially debut until Sept. 21, but eager fans will be able to get their first taste of Fox's newest singing competition this month.

The network will show a "world premiere preview" of The X Factor right before the 2011 Major League Baseball All-Star Game. The sneak peek is touted in a new commercial, which fails to mention exactly what will be shown from the series.

The preview will air on Tuesday, July 12 at 8 ET/ 5 PT on Fox.

The X Factor, from former American Idol judge Simon Cowell, will reward one lucky singer or group a recording contract and $5 million. Cowell will serve as a judge alongside Paula Abdul, L.A. Reid and Nicole Scherzinger. Scherzinger replaced original judge Cheryl Cole weeks into the auditions.
