Lupita Nyong'o went undercover at Comic Con and nobody realised it was her

"Did you see me at Comic Con?!"

That's the question Lupita Nyong'o asked her Twitter followers last night after she'd appeared on the panel for her new film.

But they probably weren't expecting her to reveal herself as the pink Power Ranger who'd been running around the San Diego convention last week.

She posted a video of herself dancing and posing with other fans, who had no idea that they were actually meeting a Hollywood actress.

The 34-year-old is the latest in a long line of stars to attend the world famous event in cosplay.

Given Comic Con is a huge gathering of superfans from around the globe, it's the only way celebrities can get around without being swamped.

And given Lupita Nyong'o is in Star Wars and the new Marvel film Black Panther, she's likely to be top of people's selfie lists.

She even managed to track down a figurine of Maz Kanata, her character in Star Wars.

Fan Cat Staggs passed by Lupita Nyong'o without even knowing.

Carrington J Tatum imagins what it would be like to "have Lupita Nyong'o unmask herself" to you.

Meanwhile, Noah J Nelson says that this disguise will become "iconic".

In 2013, Breaking bad actor Bryan Cranston decided to conceal his identity with a mask - of his own face.

The same year, Doctor Who star Matt Smith disguised himself as Bart Simpson to avoid being recognised.

Matt Smith also put on an American accent to cover his identity.

A year later, Maisie Williams donned a Spider-Man mask to blend in with the other cosplayers.

Maisie Williams reveled her identity on Instagram.

And in 2015, Ryan Reynolds went with a Star Wars theme for his disguise.

Ryan Reynolds claimed he donned the mask because he was late for his panel.
