Hours before Vince Neil was busted for DUI in Las Vegas ... he was toasting with the bubbly at a Daytime Emmy Awards party.

Here's Vince with Reality Cares founder Todd Michael Kim (left), local entertainment reporter Alicia Jacobs (center) and chef Kerry Simon (right) -- we're told the pic was taken just a few hours before Vince was busted.

Vince was arrested on suspicion of DUI -- after he had an alleged run-in with a woman who claims she smashed his camera.
