A/N: Ahahahaha! I did it! I finally got around to starting this burning flame of headcannons! My friend, the wonderful Alapest and I have been coming up with just amazing ways for Chat Noir and Ladybug to reveal their secret identities to each other on accident. And yes, this is what this is.

Drabble Idea: Chat Noir and Ladybug give each other "I'm Stupid" "I'm with Stupid" t-shirts and one of them accidentally wears it to school.

~Enjoy!


Chat Noir stood on the rooftop, smiling a cheshire grin at Ladybug, he had the best Christmas present for the girl in the entire history of great Christmas presents.

"What's with the face, kitty?" She asked, crossing her arms as the the boy dressed like a cat handed her a small paper bag with something in it.

"I don't know when your birthday is, but it is almost Christmas, so I'm giving you this now!" Chat Noir smiled, watching Ladybug as she broke her wary expression with one of amusement.

"It's only the tenth, you silly kitty," she pointed out, making no move to grab the bag, instead reaching for her pouch on her hip, also grabbing out a small wrapped box.

"That didn't seem to stop you, my lady," Chat chuckled, taking a step closer and hanging the bag by the handles on her hand.

"Stop teasing or I'll take it back," the dark haired girl scolded, tightening her grip on the bag as she handed off the box she had wrapped for the cat.

"On three?" Chat nodded and started counting with his lady.

"One, two, three!" The boy opened up his present to reveal a folded up white piece of fabric. He delicately took the fabric out and unfolded it, revealing a t-shirt with a very... interesting design.

"My lady, this is a cat, correct?" He asked, staring at the t-shirt in an unreadable expression.

"Yes, silly kitty, it's a cat." Ladybug laughed, holding a t-shirt of her own, only this one only had the words "I'm with stupid" printed on it in bold, black letters. Chat Noir no doubt had the matching t-shirt.

"Then why is... why does this cat think he's a dog person?" Chat asked, referring to the quote bubble that had the cat saying "I'm a dog person, really". He was trying really hard not to be amused with the gift, but he wasn't succeeding, his lady really knew how to make him laugh.

"I thought you were a dog person, but you're a cat, so it seemed fitting." Ladybug shrugged, tossing the empty bag in the dumpster that sat in the alley below the building they were stationed at.

Chat Noir gave a laugh, folding the shirt up before tucking it into one of the surprisingly large pockets on his suit.

Ladybug folded up her own gift and tucked it into her pouch. "Well, I think we've stalled long enough, one loop around Paris before calling it a night?" She turned a questioning look at her partner to see if he agreed with the plan.

Chat nodded, "I think so, but first-" Chat Noir wrapped his lady into a tight hug, lifting the smaller hero off her feet a bit as he swayed side to side, He laughed as she gave a shriek at the sudden contact and absence of ground beneath her feet as he swung her gently side to side.

"Merry Christmas, my lady!"

Ladybug laughed along with the boy as she hugged back, getting him to set her back on her feet, but still embracing her.

"Merry Christmas, you silly kitty."

Marinette wasn't the only one to notice that Adrien was tired, but she was the most interested with his attire. Adrien was wearing sweatpants and a t-shirt, he would occasionally wear sweats on the first day of the school week, especially if he had had photoshoots and modeling gigs all weekend, but the concerning part of his outfit was the t-shirt.

The t-shirt was a small black cat declaring itself as a dog person. The t-shirt was the exact t-shirt she had given Chat Noir just a few days ago for their impromptu Christmas gift giving. Marinette had to figure out where Adrien got the shirt, he couldn't possibly be Chat Noir, could he?

Alya nudged the dark haired girl with her elbow, trying to get her to pay attention to the lesson, finals were coming up and they were going over the review at the moment.

Marinette nodded, pushing her thoughts about Chat and Adrien to the back of her mind and focusing on the lesson, she didn't want to fail, after all.

After class, Marinette did something she had always dreamed of, she walked up to Adrien confidently and talked to him like a normal person, well, almost normal.

He was standing by himself at his locker, staring at it as he tried to think what books he needed to take home for the day.

"Hey, hi, uh, Adrien! I was, uh, I like your shirt!" She stammered, trying to collect her thoughts long enough to figure out where the boy of her dreams got the one of a kind t-shirt she made for her partner-in-crime-fighting.

"Huh? Oh, thanks, Marinette," Adrien replied groggily, visibly suppressing a yawn as he turned to face the girl. He rubbed his eyes, the sleepless nights of patrols and modeling getting to him.

"Yeah, where'd you get it?" She smiled warmly up at the boy, and he smiled back, he was starting to focus on the conversation they were having.

"Oh, my friend got it for me, early Christmas present." He shrugged, shutting his locker door, he had given up on trying to find the books he needed.

"Oh? That's nice, well, I'll see you on patrol tonight, Chat?"

"Yeah, see you then," Adrien yawned and gave a wave over his shoulder and turned to walk away, unaware that he'd let his secret identity slip out with the yawn.

Adrien got to the front doors before he realized he had not only let his alter ego be known to Marinette, but he had also left her at his locker right after he had told her.

Adrien spun around and ran back to Marinette, almost taking out three people in his haste to get to the dark haired girl that stood frozen at his locker.

"How did you, I mean, I'm not, what you heard was... What?!" He frantically spat out, his mind everywhere as the girl just stared at him in utter disbelief.

"Marinette, are you okay?" Adrien waved his hand in front of her face, trying to snap her out of her staring at him like he had grown another head.

"I can't believe it, I cannot believe it, oh my god," she finally spoke, her voice hushed as her eyes grew wide and she began to process all the information.

"You're Chat Noir, oh no, you are Chat Noir and I, oh my gosh, okay," she blinked at him, his eyes growing more panicky as she repeated his alter ego's name.

"Can we, uh, can we go somewhere else?" He hissed, grabbing the girl's hand and gently tugging her towards the door as she nodded.

It took them a short walk to get to Marinette's bakery, where they sat at the counter "watching" the shop for Marinette's mom as she went to run a few errands.

"Okay, so let me get this straight: you're Chat Noir and you have a Kwami named Plagg- yes you can have some bread, you silly kitty-!" Marinette covered her mouth, the nickname slipping out as the blond boy had a roll of bread in his hand, held up with a quizzical look in his eye.

"You're Ladybug?" He asked, setting the roll down slowly as he leaned forward, trying to read the girl's expression.

Marinette gave a small nod, her hands never leaving her mouth, even as the boy laughed at the revelation.

"Ha, I should've known, I am indeed a silly kitty, eh?" He laughed, grabbing the roll and tearing it into two halves, offering one to the girl, to his partner-in-crime-fighting.

"My lady?" He smiled as she rolled her eyes, uncovering her mouth and taking the offered piece of bread.

"You silly kitty."

They tapped their pieces together, as if toasting the secrets that were revealed, before eating the bread and talking like two long lost best friends, after all, isn't that what they were?
