Though they shared the screen for nearly a decade during the original run of "Roseanne," Sara Gilbert and Roseanne Barr had a heated falling out in 2018. That year, as the sitcom was enjoying a revival, Barr posted a racist tweet about Valerie Jarrett, the former advisor of Barack Obama.

The Roseanne stars experienced conflict because of Roseanne Barr's tweet about Valerie Jarrett, which was racist. Sara Gilbert said it wasn't how the "cast and crew or anyone associated with our show" felt. In 2019, Barr spoke to The Washington Post about her anger over what Gilbert tweeted.
