Kevin Spacey -- I Did NOT Get Paid Millions For Presidential Selfie

On "House of Cards" Kevin Spacey deals in political payoffs all the time -- but Spacey says his real pockets are clean, and says a report claiming he was paid 8 mil for a photo with Mexico's President ... is total BS.

After Spacey and President Enrique Pena Nieto took the selfie earlier this month in Cancun ... a report came out saying the actor was paid the 7-figure sum -- and a Mexican tourism official board confirmed to Forbes a payment was made, but refused to reveal the price.

However, Spacey says that's a load of crap ... tweeting, "Story about Mex Gov paying 8m or any amount for selfie not true!"
