Schulenburg was most famously known for her roles on the soap opera “Soos die wêreld draai” and on the reboot of “One Life to Live.”
A representative for Schulenburg told the Hollywood Reporter that she died in Bloomfield, New Jersey on Tuesday.
“Please don’t say Marnie lost her battle to cancer. It’s simply not true. I watched her kick cancer’s a– everyday since diagnosis,” the actor reportedly wrote.
“She is incredible. We chose to attack her diagnosis with blind optimism. We only talked about the future and continued moving forward. I don’t know if this was right but it’s all we knew how to do.”
The couple share a two-year-old daughter Coda.
Schulenburg’s first television role was as Alison Stewart in “As the World Turns.” She was the second actress to take on the role after Jessica Dunphy left the show in 2005.
“Soos die wêreld draai” also starred Jake Silbermann, Elena Goode, Van Hansis and Alexandra Chando.
Schulenburg was permanently cast for the role in 2007 and was seen until the show was canceled in 2010.
Aside from her time in soap operas, Schulenberg appeared in shows such as “Blue Bloods,” “Army Wives” en “Divorce.”
The third season of her reoccurring role in “City on the Hill” is set to be released this July.
