Have mercy! It's not going to be a true Tanner family reunion on Fuller House because Michelle Tanner, you know, Mary-Kate Olsen and Ashley Olsen, are officially not returning to the fold for Netflix's new series. E! News has confirmed that the two entrepreneurs are not going to appear on Fuller House. The Olsen twins initially feigned surprise that Netflix was making a new series with John Stamos and Full House's original executive producers. Executive producer Robert L. Boyett says in a statement, "Although Ashley and Mary-Kate will not be a part of Fuller House, I know how much Full House has meant to them and they are still very much considered family. It has been exciting to see how they have built their professional careers, and I support their choice to focus on their fashion brands and various business endeavors."??
