We're told Jason is charged with grand theft and buying/receiving stolen property ... and he was picked up Tuesday from Ventura County jail by Napa authorities after serving a 60-day sentence for crashing Britney's wedding.
TMZ broke the story ... Jason had a felony warrant out for his arrest in Napa County when he got busted in June at Britney's ceremony. Cops in Napa say Jason swiped a $2,000 bracelet from a woman there in 2015 when he was a houseguest.
As we first told you ... cops say Jason had been living in the woman's house for only a few weeks when she claims she noticed jewelry missing from her bedroom. Police say Jason later admitted to the woman he stole her diamond and sapphire tennis bracelet, valued at $2k, and pawned it off.
Now, the alleged theft is coming back to bite him.
