"Breaking Dawn Part 1" continues to be number one at the box office, despite "The Muppets" opening on a family holiday weekend. With all of the success and money "Twilight" has enjoyed, it's bound to have lots of fans in Hollywood. Plenty of people there just want to jump on the bandwagon of something popular.

However, there are a number of celebrities who appear to be genuine Twi-hards. They may start watching "Twilight" as a joke, or read to the first book just to find out what the hype is about, but it ends up hooking them. They end up talking about it in interviews and tweeting about it much more than I imagine they expected.

We already know about the obvious celebrity Twi-hards like Dakota Fanning, who won the part of Jane after admitting her fandom, and any female child star under 15 years old. Here are 10 Twi-hard celebrities that you may not know about.

50 Cent

When 50 Cent decided that he needed new G-Unit recruits, Robert Pattinson's name made his shortlist. He told MTV, "He has a big enough following to be the frontline. 'Twilight' ain't no joke." Curtis Jackson is joking. He attended the "New Moon" premiere and admitted on "Jimmy Kimmel Live" that he's a fan. There was even a minor campaign to get him into "Breaking Dawn." After all, with as many bullets as 50 Cent has taken, he may be a vampire.

Aziz Ansari

Snarky comedian and Twitter superstar Aziz Ansari decided to live-tweet his "Twilight" watching experience. Obviously, he had his fair share of jokes: "If you stop a van from hitting a girl, don't be such a d--k about it. Be like, "Look baby, I'm a vampire. That's how." #EdwardisBeingaD--k." Ultimately, he decided he loved it: "WHOA. Can anyone that has long scraggly hair in this movie turn into a wolf? That's dope! Why do people hate on this movie???! #Twilight." However, he still can't pick a team: "Still can't figure out if I'm #TeamJacob or #TeamEdward or #TeamAsianKidwithGlassesThatGoestoSchoolwithEm ..."

Sofia Coppola

The director of "Lost in Translation" and "Marie Antoinette" was on the shortlist of people that Summit considered to helm the "Breaking Dawn" monster. Obviously, she lost out to Bill Condon, but that doesn't make her less of a fan. Coppola revealed to MTV News, "I'm impressed by Kristen Stewart and Robert Pattinson pulling it off in that whole story. I just love that it's so romantic." While I like the job Condon has done so far, I can't help but wonder what Coppola's "Breaking Dawn" would have been. It would have included more Scarlett Johansson-esque awkward brooding.

Simon Pegg and Nick Frost

These British comedic actors, who starred in "Shaun of the Dead," "Hot Fuzz" and "Paul," have tweeted back and forth about "Twilight" more than smitten schoolgirls. Pegg wrote, "@nickjfrost He's effectively pushing her into Jacob's muscular and suspiciously hairy arms." To which Frost replied, "@simonpegg she's a nice girls but she keeps falling for monsters." And before you think they're just joking around, Pegg already admitted his Twi-hard-dom on Twitter: " Read the Twilight books on hols. Really enjoyed them in a sort of 'creepy old man reading delusional, horny, daughter's diary' way."

Patrick Kane

19-year old hockey star and Chicago Blackhawks center Patrick Kane likes to put on a tough exterior, but even a celebrity teen can be sold out by his mother. Kane's mom caught him reading "Breaking Dawn" -- and told the press. When asked about it, he laughed, "She would throw me under the bus like that. I watched the first three movies and was really interested ... so I decided to read the fourth book." That's cool, Kane. Hockey players should enjoy ice-cold vampires.

Ryan Seacrest

This "American Idol" and radio show host doesn't make fun of many things in popular culture. He can't afford to, because his entire schtick is appealing to the masses. So, while his radio show readings of the "Twilight" books sound snarky, I think there's genuine interest there. After all, when Pattinson came on his show in 2009, Seacrest asked about his relationship with Kristen Stewart, which was a big no-no at the time and sent Pattinson storming off. Only a Twi-hard wouldn't be able to resist asking a sensitive question that juicy.

Katy Perry

I've written about Krisbians before. They're mostly female fans who are bi-curious, but would definitely "go lesbian" for Kristen Stewart. Well, count Katy Perry as a celebrity Krisbian. After her song "I Kissed A Girl" broke big, she was asked which girl she'd most like to kiss. Her answer? You guessed it.

Barack Obama

I'm not saying the President of the United States sits in the Oval Office Googling R.Pattz and K.Stew gossip when he should be dealing with the national debt, but Obama has admitted to enjoying the "Twilight" books and discussing them with his oldest daughter Malia. You may argue he's just saying that to appeal to voters. But c'mon, how many Twihards are even old enough to vote? Maybe his term has been disappointing because he's so obsessed with Male Twi-hard updates on Twitter?

Adam Lambert

You probably saw this one coming. Of course popular goth rocker Adam Lambert would be a Twi-hard. The surprising thing is how hardcore he is about it. He's talked about it in many interviews, even if the interviewer doesn't bring it up. And he really lobbied hard to be involved with the film series, even going as far as to bite Catherine Hardwicke's neck. He must have tried too hard and freaked out producers.

Rosario Dawson

Known for movies like "Kids," "25th Hour" and "Death Proof," this New York native has made a name by playing tough-chick characters. Despite Rosario Dawson's image, she can't help admitting her soft spot for sparkly vampires. "I just read the first book, it's ridiculous, it's like crack cocaine. I read it for 10 hours straight until I finished it," Dawson told People. Her analogy to drug addiction was no joke. Like an addict, she couldn't have the books near her while working; otherwise she'd blow off responsibilities to read. In fact, she ignored her family one Christmas vacation to read "New Moon," "Eclipse" and "Breaking Dawn."
