Kevin Hart Ties the Knot in Grand Style

Kevin Hart sealed the deal Saturday at a super fancy wedding ceremony in Oprahland.

Kevin and Eniko Parrish exchanged vows at a grand estate in Montecito, CA ... a few miles south of Santa Barbara.

It was a long time coming. Kev and Eniko got engaged 2 years ago ... but we're guessing the delay might have been because he was a little busy.

200 people watched as Hart's 8-year-old son, Hendrix, did the honors as best man.

The reception was pretty awesome ... complete with a Ferris wheel and Merry-Go-Round.

Congrats!!!
