Oprah's HUGE Finale Party -- Seinfeld, Hanks, Stevie!

Tom Hanks, Jerry Seinfeld, Alicia Keys, Michael Jordan, Gayle King, Kelsey Grammer and Stevie.Oprah arrived to the party around 12:30 AM and was AWESOME -- shaking hands with just about every single person at the shindig.  As for Stedman -- dude must have had the night off because he was MIA.

Now for the food -- we're told Oprah had multiple service stations offering everything from shrimp cocktail to diced lobster tails and pulled pork sandwiches.

The dessert bar consisted of O's favorite sweets -- including a "make your own cotton candy" station.

And of course, there was BOOZE -- besides an open bar serving top shelf liquor, O had a GIANT tequila station ... because Oprah loves the agave juice.www.facebook.com/emmanuelsamuko
