"Oh ya, they killed her", Barr said.
"Oh yeah, they killed her", Barr said.
Barr, 65, admitted she has accepted her fate and the fact that the show is moving on without her.
ABC has not publicly confirmed or denied Barr's claim. However, she never wanted her character to die from it.
"The first people who called me were my African-American family members and comics", she said.
On her character dying via opioid overdose: "I'm not 100% sure, but my spies there, they said that". It's hard-hitting subject matter, and one that is sure to get the audience talking when it's revealed Roseanne ultimately dies because of her addiction. "It's done. It's over", she said.
On May 29, ABC announced that it had cancelled Roseanne just hours after Barr apologised for published a racist tweet directed at a former aide to President Barack Obama.
As for her future plans, Roseanne, who's of Jewish heritage, explained her intentions to study her Jewish background a lot more when she's in Israel. It's done, it's over, there's no fight left.
"I want to stay away from it", the actress remarked. "I did what I had to do to save my own life and I did it".
