TMZ has learned Christina Milian officially tied the knot with music producer The-Dream in Vegas last week ... at a place famous for its "Drive-Thru Tunnel of Vows."
It all went down close to midnight at the legendary Little White Wedding Chapel -- the same place Britney Spears married that Jason Alexander dude back in 2004.
According to Milian's marriage license, the two said "I Do" at exactly 12:00 AM Friday morning.
We're told Milian rented her wedding dress for $200 (including shoes and veil) and The Dream rented his tux for $100 (including shoes, tie and vest).
It's no big surprise they got hitched -- as we first reported, the two applied for a marriage license last month ... and those things are only good for 90 days.
