Wednesday fans do double take as they spot Princess Diaries legend in season 2

WARNING: This article contains spoilers from Wednesday season two.

Wednesday season two, part one, has landed with fans taken aback to see a 1990s star brought into the fold.

Netflix debuted its second series of Wednesday on Wednesday, August 6, which sees the forever morbid Wednesday Addams (played by Jenna Ortega) return to Nevermore Academy.

It doesn't take too long before she gets stuck into another mystery, which was kicked off with a vision of Enid Sinclair's (Emma Myers) death before evolving into so much more.

Murderous crows had started killing off people and Wednesday was determined to find out why and at one point, believed Tyler Galpin might have something to do with it.

So she ventured to the Willow Hill Psychiatric Hospital where he was being kept but before the teen could come face-to-face with Tyler, Wednesday had to endure the cheerful Judi (Heather Matarazzo).

Judi works as the executive assistant to chief psychiatrist Dr Rachael Fairburn (Thandiwe Newton) who is in charge of Tyler's care.

Wednesday has a brief conversation with Judi as she waits for her meeting with Dr Fairburn but it was apparent the sarcastic youngster was far from impressed by her happy demeanor and colourful jumper.

While her initial scene was short, fans were quick to do a double take as they realised Judi is portrayed by actress Heather Matarazzo.

The 42-year-old has been in various films during recent years such as Paint, The Zombie Wedding, and Booger, she is by far best known for starring in 2001's The Princess Diaries.

Starring opposite Hollywood actress Anne Hathaway, Matarazzo portrayed her outspoken best friend Lilly Moscovitz.

She also went on to star in the 2004 sequel and also played Martha Meeks in the horror films Scream and Scream 3.

Taking to Reddit, someone remarked: "Guys it's Lilly. From Princess Diaries.

"Being overshadowed all those years as the bestie to royalty obviously led her to madness and the dark side."

Another commented: "I literally spent that whole scene trying to remember who she was." As a third excitedly pointed out: "OMG is that lilly from The Princess Diaries."

What fans were not expecting, however, was for Judi's part to be amped up in the midseason finale as it's revealed that Judi is in fact The Avian in control of the killer crows.

She has been trying to put a stop to Wednesday getting closer to finding out that Stonehurst (Phil Philparr), her father, had been experimenting on outcasts to extract their powers and give them to "normies".

Judi, who was a "normie" before successfully becoming an Avian, was continuing his work but what will happen in part two now her secrets have come out?

Wednesday is available to watch on Netflix.
