Francesca Eastwood's marriage to Jonah Hill's brother will end faster than you can say Britney Spears and Jason Alexander ... because she's getting the week-long marriage annulled ... TMZ has learned.
Sources close to the regretful couple tell us ... the notion of getting hitched was fueled by alcohol -- and lots of it. Francesca and Jordan Feldstein ended up in a cheesy Vegas wedding chapel and took their vows amidst faux greatness -- an Elvis impersonator.
Francesca had immediate regrets. We shot her the day after the nuptials and she wasn't wearing a wedding ring.
We shot Clint Eastwood a few weeks ago asking for marriage advice and he told our photog to not rush into anything.
Guess Francesca should have listened.
