One shared: "Wow. Liz Sheridan from #Seinfeld passed away too? Just 5 days after her birthday and not long after Estelle Harris passed away.
She knew how to bring the type of energy her character needed."
A second wrote: "What are the odds that the two iconic Seinfeld moms would die two weeks apart? Rest in Peace to the iconic Liz Sheridan, a Broadway actress who famously dated James Dean.
"She was also Jerry's mom and follows Estelle Harris. She died 2 weeks ago and was George's mom."
A third penned: "The characters George Costanza & Jerry Seinfeld both lost their moms within 2 weeks of each other. R.I.P Estelle Harris & Liz Sheridan, thanks for the laughs."
The actress has sued Justin Baldoni for sexual harassment.
