5+ Celebs Who Just So Happen To Have The Exact Same Name

Kate Hudson's celebrity name twin: Katheryn Hudson, otherwise known as Katy Perry.

Katy Perry was born Katheryn Elizabeth Hudson, and actually performed under the name "Katy Hudson" when she was trying to make it as a gospel singer.

She didn't want to be confused with Kate Hudson!

That choice followed her to super stardom. She is now a judge on American Idol, has multiple awards and nominations, and owns her own accessory line.

She's a mogul, too. While she started out in movies, she now devotes most of her time to her own fashion venture, FabLetics.

She still appears in films from time to time, like the upcoming Australian musical, Music.

There's no stage names here, just two women kicking major butt in their respective fields.

Because they share the same name, people often confuse them.

After the actress made a passionate speech about pay equality, commenters went to the wrong Instagram to congratulate (and criticize).

"When you go to my profile, you search for the ‘Michelle Williams,’ I am black. OK?"

"So I am trying to figure out why in the world I am getting cursed out in my comments for Michelle Williams’ speech, which I thought was her truth, which I thought was awesome."

So, remember: one's an actress, one's a singer. And they're both queens.

It happened, "when I took my daughter to see Stevie Wonder. They were like, 'huh?'"

Apparently, the crowd was expecting the other Michelle. However, when she explained, they were all cool with it.

You know when you go to make a new social media profile, but someone else already has the @ you wanted?

That must have been a big issue for actor Adam Scott and golfer Adam Scott.

Anyway, you may know actor Adam Scott from the greatest comedy of all time, Parks and Recreation.

The other Adam Scott is an Australian professional golfer who was the #1 golfer in the world in 2014.

Crazy, huh? Michael Keaton's real name is, in fact, Michael Douglas.

He didn't want to change his name — he was actually forced to, due to the Screen Actors Guild rules on the subject.

The first was Mike Douglas, a daytime television host. The second, of course, was the iconic Michael Douglas.

Michael Keaton said he picked his new last name out of a phone book he randomly opened.

Mark Wahlberg: actor, producer, burger chain owner, has an h in his last name.

Mark L. Walberg: actor, tv personality, game show host, does not have an h in his last name.

They both like to take pictures of themselves after working out.

Mark L. Walberg has a pretty good sense of humor about sharing his name: his Instagram bio contains the phrase, "not a wahlberger."

These two have more in common than most of the other celeb name twins on this list: they're both in the same industry.

The music industry, I mean. I feel like it's a given that they're in the entertainment industry. Anyway...

Randy Jackson is a Grammy-award winning producer. You probably remember him from when he was a judge on American Idol.

Randy Jackson is the brother of Michael Jackson, and a musician in his own right.
