  • Stunned followers were also surprised; thousands didn't know it was her

Several Mean Girls fans may find themselves in the Burn Book after admitting that they had no idea Rachel McAdams had played the role of Regina George – the original Mean Girl – because she wore a blonde wig in the film.

A TikTok user posted the stunned video after realizing a blonde McAdams played the Queen Bee in the 2004 film – and many followers were equally shocked by the news.

“Rachel McAdams wore a $20,000 wig when she played Regina George in Mean Girls because she didn't want to bleach her hair, and after the movie it sold for $600,000.” user @sakuraxea wrote on the 10-second clip.

The video has been viewed more than 15.2 million times, with more than 3,300 comments from stunned users who were unaware that the Queen of North Shore High School was played by the now 45-year-old actress.

β€œI was a year old today when I found out Regina George is Rachel McAdams,” one user stated.

“I always thought Regina and The Notebook actress were different,” one surprised follower commented.

“It was like last week when I found out Regina was Rachel McAdams and not Lindsay Lohan (I don't know why I always thought that),” another agreed.

'The personality change from Mean Girls to The Notebook. Really a star,' he said.

“Omg I NEVER thought this was a wig,” one stunned user wrote.

“So they weren't kidding when they said her hair was insured for $10,000,” another joked, referencing the iconic line from the film.

In reality, McAdams wore the blonde wig because she was filming The Notebook, another 2004 blockbuster, at the same time.

News of the wig came to light in a 2016 interview with Rajiv Surendra, who played legendary mathematician Kevin Gnapoor in the film.

When speaking with Seventeenthe actor revealed that McAdam's blonde locks were “not her hair in the movie.”

β€œThey had a wig made from human hair by a very well-known wig maker from the town of Stratford, Ontario,” he explained.

He went on to explain that he's not sure if it's true, but he heard that the actress didn't want to bleach all of her hair.

“So the front part was bleach blonde, so that was her real hair, but the wig was fake,” he explained.

'I remember regularly walking into the make-up and hair trailer and seeing the wig being washed.

β€œThey washed it and put a little shower cap on it and attached the hairdryer to it to dry the wig,” he recalls. “It looked like a $10,000 wig.”

The actual cost of the wig is unknown, as is how and where the wig was sold.
