1. Darren Criss
Technically when Criss is a first named it's spelled Chris, but regardless, Darren's version still works. And the fact that his 'Glee' character, Blain Anderson, has two first names too? Things are just getting weird.
2. Lea Michele
The 'Glee' star's real last name is Sarfati, but Lea went by Lea Michele in her professional life because kids in school used to make fun of her actual last name. Why are people so mean?
3. Adam Brody
The 'OC' star's last name is actually his real last name, but Brody could definitely pass as a first name, too. Brody Jenner, hello!
4. Adam Scott
And speaking of hot guys named Adam, here's Adam Scott. Scott Adam or Adam Scott, he's a hottie either way.
5. Elton John
Sir Elton's birth name is Reginald Kenneth Dwight so we're not quite sure how Elton John came out of that, but he's a musical legend so we're just going to leave it alone and not ask questions. OK?
6. Keri Russell
Is Keri secretly related to Kurt Russell? Not that we know of, but Russell is her birth-given last name, for realsies.
7. Matt Damon
When we think of Damon we think of the hot guy on 'Vampire Diaries,' but we bet Damon as in Matt comes to mind, too.
8. Nicole Richie
Lucky Nicole snagged the last name Richie (also a man's first name, FYI) since her dad is Richie as in Lionel.
9. Anderson Cooper
Cooper is one of those names that can be a first or a last name, and Anderson is one of those names that can also be a first or a last name, so yeah.
10. Shay Mitchell
'Pretty Little Liars' Shay Mitchell's real name is Shannon Mitchell, but still, Mitchell is a guy's first name, so she makes sense on this list.
11. Ricky Martin
There are quite a few celebs with the last name Martin—Steve Martin being at the top of our list—but Ricky Martin is probably our favorite, if we had to choose.
12. Amy Adams
Fine, there's an S at the end of Adams, but Amy and Adam are both first names, no matter what syllables you add to the end of it.
13. Phillip Phillips
Were Phillip's parents playing a joke on him or something? We're glad they gave him the same name twice though. It works to our benefit when it comes to this slideshow.
14. Farrah Abraham
Granted we haven't heard of anyone with the first name Abraham since, like, the Biblical times or like, Abe Lincoln, but regardless, it counts!
15. Keegan Allen
'Pretty Little Liars' Toby on-screen is named Keegan Allen in real life.
16. Meg Ryan
Meg Ryan's birth name is Margaret Mary Emily Anne Hyra. That is all.
17. Zachary Levi
Zachary's real last name is Pugh (like the dog we guess?), but instead he uses his middle name as his last name professionally.
18. Holly Madison
Holly's given name is Hollin Sue Cullen. Maybe if 'Twilight' was around when she became famous she would've kept her last name and pretended she was related to Edward?
19. Max George
Max George of The Wanted has two first names, but we don't even care because he's so hot his name would be anything in the world and we'd still date him.
20. Rachel Zoe
Rachel's real last name is—wait for it—Rosenzweig. She dropped it and took her middle name as her last name when she started out in the fashion industry because she was afraid it sounded "too Jewish." Makes sense.
21. Joey Lawrence
Personally we like Lawrence way better as a last name than a first name, but maybe that's just because when it's a last name it reminds us of Joey? It's hard to say.
22. Liv Tyler
Obviously we could've chosen Liv's dad, Steven Tyler, to feature here too, but we opted for Liv instead just to let you know that her real name is Liv Rundgren. We can't make this stuff up.
23. Sean William Scott
This guy basically has three first names instead of the usual one first, one last. One of the many reasons why we love him (with 'American Pie' being the biggie, of course).
24. Jenelle Evans
The 'Teen Mom' star sorta kinda changed her last name to Rogers when she married Courtland, but whether her moniker is Rogers or Evans, both qualify as first names in our book.
25. Justin Bobby
Justin's real last name is Brescia, but if Bobby was good enough for the entire cast of 'The Hills' it was good enough for us. We honestly can't picture Justin's last name as anything else.
26. Kyle Richards
Kyle's another one of those celebs that has names that can be interchangeable. Kyle Richards? Richard Kyle? Well, we guess she's not a guy so the first one makes more sense.
27. Kevin James
Kevin James, Lebron James, whatever kinda James, this last name rocks. Kevin's real name is Kevin George Knipfing though so do with that what you will.
28. Joshua Jackson
Josh's full name is Joshua Carter Jackson, which means, like Sean William Scott, he has three first names too. So cool.
29. Jonathan Taylor Thomas
Add JTT to the three-first-names club, too. Is it just us or are all the three-named guys hot? We do NOT think that's a coincidence.
30. Selma Blair
Selma's given last name is Beitner, but she opted to use her middle name as her last name once she became an actress. Maybe it was for the same reason that Rachel Zoe did, which was to sound less Jewish?
31. Evan Peters
Evan Peters and his girlfriend Emma Roberts both have last names that could double as first names. So cute, right?
