Deen, 66, was scheduled to be interviewed last Friday about the media firestorm ignited by her recent admission she regularly used the N-word in the past, but she canceled her appearance at the last minute.

She confirmed via Twitter Monday she will definitely show up for Wednesday's edition of "Today."
"She has told us she will be here this time," Lauer tweeted.
