Damon shed some light on the situation on last night's "Celebrity Apprentice" -- when Donald Trump asked why Damon didn't try to ask Henry for money during a fundraising competition.
Long story short ... Damon says he's not sure they still "love" him out in Beantown and says he hasn't spoken with Henry in a while.
Then there was this exchange ...
Trump: "I think you'd be able to call John Henry. He'd give you whatever you want."
Damon: "He did not do that back in 2005. So ..."
Sad.
