Mike Tyson -- Gut Check

Ear-snackin' Iron Mike Tyson looks like he's getting into shape -- pear shape!

Mike, who once said, "I guess I'm gonna fade into Bolivian," [sic] now looks like that won't happen.

The former champ was spotted pounding the pavement in Beverly Hills ... which probably means that a reality show is just around the corner.
