Even a triple Tanner-Fuller-Gibbler wedding wasn't enough to lure Michelle back for the final season of Fuller House . And in the words of Stephanie Tanner, how rude! Okay, it's not really rude; Mary-Kate and Ashley Olsen made it clear from the moment the reboot began that they've left acting behind. The former child stars are now successful fashion designers with two major lines to run (The Row and Elizabeth and James), and given that they were 8 when Full House ended, it's understandable they're not quite as attached to the nostalgia factor as their co-stars.
