The upcoming JustSpotted.com wants to offer users information on the real-time whereabouts of 7,000 celebrities. The difference is JustSpotted, which is scheduled to launch Tuesday, will harness the power of Twitter to help hunt down stars, according to a report in The Hollywood Reporter.

JustSpotted executives have struck some kind of partnership with Twitter that enables them to get access to Twitter posts from people who spot stars in public, the trade magazine reported.

"Proprietary technology uses 'natural-language' filters to figure out which tweets pertain to celebrity sightings," The Hollywood Reporter said in its report.

This is obviously a twist on Gawker Media's Gawker Stalker, which takes a less techie approach to reporting on star sightings by relying mostly on e-mail tips from readers.
