Nick Young Vegas Wedding To New GF

Nick Young tried to pull a fast one Friday night -- leaving many to believe he'd gone off and married his new GF Paloma Ford -- but we've learned it was just a sham.

Young put up and quickly deleted a pic of a pamphlet from a famous Vegas wedding chapel with the caption, "she said yes." However, we called up the place and they told us there was no record of Young or Ford tying the knot in their system.

There's always a chance the pic was posted as a decoy for another secret wedding location ... but we're skeptical.

Pretty interesting considering we got Nick just last month and he told us he hopes his ex Iggy Azalea marries French Montana.
