Emma Watson has perfect response to the Emma Roberts mistake in Harry Potter reunion

Emma Watson has poked fun at an amusing mix-up that producers made on Harry Potter 20th Anniversary: Return to Hogwarts special via social media - and fans are loving her sense of humour.

During the reunion, Watson who played Hermione Granger, reunited with co-stars Daniel Radcliffe and Rupert Grint take a trip down memory lane to commemorate the franchise’s anniversary.

At one point during the show, the trio reminisced about their childhoods.

As Watson described what her childhood was like, a sweet photo of a young girl wearing Minnie Mouse ears appeared on the screen during the segment.

But it wasn’t Emma Watson, instead, it was another famous Emma... Holidate and American Horror Story star Emma Roberts.

The photo of Roberts sporting Minnie Mouse ears was posted to her Instagram account back in 2012.

Fans too quickly noticed the mistake and took to social media to share the blunder.

After the mistake circulated online, Watson herself took to Instagram and posted to her 65.4m followers the photo of the young Roberts and in the caption joked: “I was NOT this cute, @emmaroberts #emmasistersforever,” along with a laughing emoji.

It’s safe to say Harry Potter fans loved the fact that Watson directly acknowledged the fault and had the sense of humour to joke about it.

One person said: “HAHAHAHAHAHAHA NOT EMMA ACKNOWLEDGING THE ERROR.”

“The emmaverse is real,” another person wrote.

Someone else added: “FINALLY the queen herself setting the record straight for us once and for all.”

“Omgggggg yessss love that you are leaning into it,” a fourth person replied.

Meanwhile, HBO Max themselves on their official Instagram account also joked at the error on their part with a wizarding comment referencing the film franchise: “Are we sure this wasn’t the effect of a Polyjuice Potion?”

Roberts soon spotted Watson’s dedicated post to her, she reshared it on her Instagram story and wrote: “Haha I don’t believe that!”

In response to eagle-eyed fans spotting the error, HBO producers corrected the mistake with a new version and said in a statement: “Well spotted Harry Potter fans! You brought an editing mistake of a mislabeled photograph to our attention. New version is up now,” Deadline reported.
