At a Hallmark Channel party earlier this month, Fields, who is not from Pittsburgh, said she likes the Steelers and especially coach Mike Tomlin.
"I thought when head coach Mike Tomlin was running on the sidelines and all that kind of thing, that was cool," she said.
Fields said with "For Better or For Worse" she was eager to get into business with Hallmark.
"That was a big draw for me because we had already started dialoguing with them about other projects and seeing what synergy existed between my brand and theirs," Fields said.
She said working with Whelchel offers a comfortable sense of timing but otherwise it's different from when they worked together on "Facts of Life."
"The characters are different and you are different," Fields said. "She's grown with grown children and I'm grown with much younger children. ... Having the history comes into play more so for off-camera, knowing you're not gonna end up on set with a nut, a fool every doggone day."
