MJ's 'Thriller' Jacket -- Got $400k Layin' Around?!

Michael Jackson's iconic red jacket from the "Thriller" video is hitting the auction block in Beverly Hills in a few weeks -- and it could be yours ... if you've got a spare $400,000 to blow. 

The jacket -- which MJ personally autographed to his former costume designers -- is expected to fetch between $200k and $400k ... though we wouldn't be shocked if it soared past half a mil.

The jacket is one of several MJ items featured in the Julien's Auction event on June 25 and 26. Among the more interesting pieces -- the wig Michael wore at his "This Is It" news conference in London and a glove he wore at the American Music Awards.
