That wedding Tara Reid just couldn't shut up about -- she should've shut up about ... because she now admits the marriage was never legal.
Tara seemed totally out of it at LAX when a TMZ camera guy asked if she and her husband could win the Newlywed Game.
While not quite, "In the butt, Bob" -- Tara's slurred response was still pretty awesome ... as she confessed she was "never really married."
You might recall, Tara and Zack Kehayov (above) had a surprise wedding in the Greek Isles in August ... which she tweeted about endlessly. Tara says she and Zack never made it a legal union here in the U.S.A.
Tara's rep hasn't gotten back to us yet.
My Marriage is BOGUS!!
