Builder to Keyshawn -- Gimme the Damn Money

Retired NFL receiver Keyshawn Johnson has caught passes for the Jets, Buccaneers, Cowboys and Panthers ... but now he's been accused of dropping the ball on more than $1 million in payments to a construction company that worked on his house.

Gordon S. Gibson, Inc. has just filed a lien on Keyshawn's Calabasas, CA home, claiming the ESPN broadcaster owes them $1,115,500 for "supervision and construction of the Johnson residence."

According to the docs, Johnson's tab is getting bigger by the minute -- gaining 10% annual interest since January 14.
