The change comes about after Alexis long lost son Adam brutally burnt his mother's face off.
It was hinted previously that Elizabeth would be taking over the role when Adam pointed out how similar the two looked in an earlier episode.
Nicolette, who left the show to take care of her terminally ill mother told TVLine earlier in the year “I am hopeful that my fans will embrace my successor with as much passion as they embraced me.”
