Spoiler alert ... Roseanne Barr's character on "The Conners" was killed off by an opioid overdose.
The series premiere of the 'Roseanne' spin-off jumped right into Barr's death ... with writers wrapping up her storyline a mere 5 minutes into the show.
Turns out ... Roseanne had it right last month when she revealed her opioid OD in a gigantic spoiler.
Getting killed off the show was a foregone conclusion. You'll remember ... Barr got the ax from the "Roseanne" reboot only hours after she posted a tweet comparing former Obama aide Valerie Jarrett to the "muslim brotherhood & planet of the apes."
