Kevin Hart's call to action "Get f***** up with me!!!" ... that's what he told his boys in Vegas, and his birthday bash looks a lot like a bachelor party.
Kevin's been in Vegas for a few days and partied at Omnia Tuesday night, when he told the crowd, "I'm getting married."
Kev's been engaged to Eniko Parrish for 2 years.
Marriage ... it's in the air.
1:08 PM PT: Kevin posted on Snapchat he's super hung over ... we can only imagine.
