Usher will stop by Universal Studios Hollywood Tuesday, October 3, at the Globe Fountain to tell "Extra's" Mario Lopez all about the Megastar app. 

The eight-time Grammy winner is an investor, creative director, headline celebrity mentor and judge for the world’s largest crowdsourced talent competition.

This innovative mobile competition, which officially launches today, will feature performers from around the world with a diverse array of talent competing to win $1 million.

Aspiring artists are invited to upload auditions to the Megastar app for a chance at the top prize.
