20 Celebrities on Their Celebrity Crushes

It's hard to believe that Ariana Grande is the one fangirling over someone else, but it's 100% real. "My childhood crush, like, my lifelong crush, it kind of all goes together—it's Jim Carrey," Grande said on Live with Kelly and Michael in 2015. "I love him so much."

When Ariana finally got the chance to meet Carrey, he was everything she imagined he'd be—and more. "He was so over-the-top nice, and perfect, and just as I hoped he'd be. [He said to me in] his classic Jim Carrey, 'Nice to meet ya. Thank you. Remember, be nice.' I was like, 'Oh my God, you're so cute. I love you.' I was like, 'Wow, help me God, thank you,'" she gushed.

Jack Black naturally has a thing for funny girls, and it's no surprise that Amy Poehler would be his crush. "I'm always attracted to a good sense of humor. Ever since I saw Amy Poehler on Conan O'Brien where she played Andy Richter's crazy sister with the braces, I was like 'oh, okay. That girl is incredible,'" he said to W in 2013.

The whole world seems to be crushing on our June cover girl, but Selena had a childhood fantasy of her own, of her Ruddlerless costar Billy Crudup, based on the 2000 movie Almost Famous: "I had a crush on him," she came right out and said to Jimmy Kimmel in 2014. "I went through my whole Almost Famous phase, so I was like Penny Lane for a good month—I wore the outfits and had the hair and the glasses...and then, I found out I was going to be a part of the movie [with Billy] and it took me a minute at first, because I kind of had a little bit of a crush on him!"

Hathaway admitted to Jon Stewart himself in 2008 that he makes her swoon a little bit. "By the way, I'd just like everyone to know that all I heard right there is 'buzz buzz buzz.' I'm sitting across from Jon Stewart! It is so cool to be here!" she announced to the audience.

Though Stewart was too modest to buy it, Hathaway insisted that many of her friends felt the same exact way. "No, seriously, every girl that I said I was coming on this show…was like 'I have the biggest crush on him!'"

If you ever feel extremely single, just remember that even Ryan Gosling has been let down in the love department. Gosling told Glamour in 2013 about his unrequited preteen affection for fellow Mickey Mouse Club star Britney Spears. "Britney was a sweetheart. She lived right above me, the girl next door. The little girl I used to play basketball and spin the bottle with." In an insane twist of the universe, Spears didn't return his feelings, choosing her other teeny-bopper costar and fellow denim lover, Justin Timberlake, as her BF.

"I have the biggest crush on Will Ferrell," Streep, queen of everything, said in a 2015 Vanity Fair interview. She added the true reason, confirming her non-cougar status. "I love him in every film he does. I mean, Ryan Gosling could be my child. I'm not going to have a crush on a child. Will Ferrell is a man," she revealed.

It's only fitting that the former Punk'd host would make a bet with his friends on teen crush Jen Aniston. He got real in 2011: "I was 17 years old and she was my screensaver."

He described the plan to get a date with Jen, which she kindly turned down. "So I make a bet with my buddy. I'm probably 17 years old. I said to him, 'I bet you $1,000 that some day I will go on a date with Jennifer Aniston.'"

When MTV asked about her first celeb crush in 2012, Reese answered sheepishly, "I have to say probably Johnny Depp in 21 Jump Street. I just had a really major crush on him. I used to pull pictures out of Teen Beat and put them on my wall."

Reese responded to the question of whether or not she ever professed her love to Depp. "I don't think he knows," she laughed. "I'm not sure it would faze him; I'm sure he's heard that quite a bit."

"I think Steve Carrell is so sexy," Hale told Lucky magazine back in 2013. And just in case the whole world, including Carrell, was unaware of her affections, Hale reaffirmed her feelings with this tweet that same year: "Steve Carell is my dream man. That's all."

At the risk of sounding like a stalker—her words—Roberts acknowledged her obsessive teen behaviors on Live with Kelly and Michael in 2015. "I'm literally getting flushed thinking about it. Remember when you are younger and you have crushes where you are sobbing just looking at a poster of them? That's how intense it is," she blushed.

It didn't end there, according to Roberts. "I used to collage my whole room for hours with pictures of Jonathan Taylor Thomas and a couple of other people," Roberts said. "It was a little creepy, almost. I think it was a little stalkerish."

There seems to be a mutual girl crush situation going on between Adele and RiRi. "If Rihanna wanted me, I'd do it with her. She's hot," Adele said in 2012. "She had pinstripe flares on. She whipped them off and there were her stunning thighs. I said to all my girlfriends, 'Are you feeling a bit gay right now?'"

Rihanna responded, playing along with Adele's game. "Really I came to the BRITS to stalk Adele, she said. "It was nothing about the awards or the performance, for me it was just to see Adele again. She doesn't know the depth of my affection, just the surface. She has no idea."

Jason Sudeikis responded in a 2013 Elle interview to a comment about his major college crush on Ellen DeGeneres. "It was 100 percent for real," Sudeikis said. "It was the gorgeous blue eyes. And she's hilarious. That's all it takes for me."

We know from Bridesmaids and Pitch Perfect that Rebel isn't timid, but her words regarding her infatuation with Channing Tatum prove it. "I'm too nervous to even say it. What if he sees this and is like OMG, Rebel Wilson is my celebrity crush? Yeah, let me get divorced from my wife and come and find out where she lives. Alright, Channing, if you wanna do that, my address is 948 Blueberry Road," she told W candidly in a 2013 interview.

Dame Helen Mirren has eyes for a particular American action flick star, Vin Diesel. "It came from me watching him make a speech once at some ceremony. He was just so smart and so funny and so cool, and I just sort of fell a little bit in love with him right there and then. Vin, I love you. I love you, Vin. You don't know who I am, but I still love you," she professed on Late Night With Seth Meyers last year.

Lauren Conrad, like just about every other tween girl in America, once worshipped Justin Timberlake. When asked to specify which era of Justin caught her fancy, she clarified in 2014, "Like, the hair, license-plate-around-the-neck Justin in his prime."

"I just remember I liked you," Kidman told Fallon, who has appeared twice now on the celeb crush list, in a hilariously open dialogue during her appearance on his show in 2015, recounting the story of their meeting and potential for a date years ago. "So Rick, our mutual friend, says 'Oh, you know, Jimmy wants to meet you and you can go over to his apartment'...and I'm single, and I'm like 'Yeah, cool,'" she explained.

"And after about an hour and a half, I was like 'he has *no* interest. This is so embarrassing,'" Kidman laughed. It was clear that Fallon, busy living his "video games and sneakers," lifestyle, as he claims, was too clueless at the time to realize the opportunity he was passing up.
