Taylor Swift Reportedly Attended NFL Games "Privately" Before Making Her Relationship With Travis Kelce Public, And 14 Other Times Celebs Hid In Plain Sight

You may have fantasized about what it's like to be famous, but plenty of celebrities have fantasized about what it's like to not be famous. Some of them have even acted those daydreams out, whether it's in preparation for a role or for personal reasons.

Here are 15 times celebrities went undercover as "normal" people:

1.To prepare for the titular role in Bridget Jones's Diary, Renée Zellweger worked undercover at the publishing company Picador for "a month or two."

2.In 2015, Aubrey Plaza played on the women's recreational basketball team the Pistol Shrimps (which is the focus of a documentary of the same name). However, when she tried to be traded to her sister Natalie's team, the Spice Sqirls, she was rejected, so she "decided to play in disguise as somebody else" and donned a blonde wig and goggles.

3.To get ready to play the stripper Destiny in Hustlers, Constance Wu went undercover working at a real strip club. She put fake tattoos on her neck and wore hair pieces.

4.To prepare to play Peter Parker in Spider-Man: Homecoming, Tom Holland went undercover as a student at The Bronx High School of Science in 2016. He shadowed Arun Bishop, a real student who was a senior at the time, and pretended to be his cousin Ben.

5.In 2024, Kevin Bacon told Vanity Fair that he once "went to a special effects makeup artist, had consultations, and asked him to make [him] a prosthetic disguise." Wearing glasses, a fake nose, and fake teeth, he went to The Grove, a mall in Los Angeles, where no one recognized him.

6.But that's not the first time Kevin Bacon went undercover! To prepare for his role as Ren McCormack, a teenager who moves to a small town, in Footloose, he "went and had that same experience for a day" at a real high school. Only the principal and guidance counselor knew his true identity.
