Nicki Minaj and Kenneth Petty only got hitched because the clock was ticking on their marriage license ... and they'll have a big bash with friends and family later.

Nicki and Petty got married Monday at a private home in L.A. We're told the only people who attended -- aside from the bride and groom -- were a minister and several members of their immediate families.

As for why the rush ... their marriage license expires at the end of this month, so they had to pull the trigger or start all over again at square one. It's only good for 90 days.
Nicki and Kenneth are going the route of Justin and Hailey ... a small, no-frills wedding followed by a church service and massive celebration. As for Nicki and Kenneth ... we're told they're in no rush, but they will plan a big event.
