Andre 3000 -- Picks Up Random Girl In Uber ... Takes Her To 'Waves' Studio Session!!

An Andre 3000 fan got the surprise of her life after hopping in an Uber with the rapper and witnessing some music history.

Sources close to 3000 tell TMZ he landed in L.A. Friday night for a studio session with Kanye to put some finishing touches on "Waves". He meant to order a single passenger Uber but accidentally got an "Uber Pool" -- where one driver picks up multiple people -- and another passenger got in with him.

After some small talk, Andre and the girl hit it off, even finding out they'd lived in the same place.

So Andre decided to bring her along to the studio with him, introducing her to Kanye, French Montana, Diddy, Kid Cudi and 2 Chainz when they got there.

We're told the girl didn't stay long, but what a freakin' awesome experience.
