It's not often you're driving next to your favorite NASCAR racer Kyle Busch.
After a big win at the STP 500 in Maryland on Sunday, Kyle Busch was stuck in traffic with his wife when he decided to say a subtle hello to the car next to him.
Busch says a simple, "sup?" to the car next to him, and his wife captures the next car's entire reaction on camera.
Mega fan Darienne Breazeale only took a moment to process before she sprung into action. She stuck her head out of the window and shrieked: "Oh my god!"
"I thought I was hallucinating" Breazeale later told InsideEdition.com. "I have been a fan ever since he started racing. I could have won the lottery and would not have been as happy as I am right now."
"I freakin' love y'all!" she can be heard in the video, yelling out of the passenger seat window.
In the driver's seat, Busch reaches over and asks for her hat, stamped with his signature No. 18, to sign as he inches his way forward in traffic.
Little did Busch know, she even caught the hat during the race, when one of his crew members threw it into the stands.
He hands the signed hat back to Breazeale, and drives off. In the background, she can be heard saying, "I'm so happy you won."
"I haven't taken the hat off since," Breazeale later admitted to IE.com. "I probably should though because I don't want to mess it up!"

When Busch later posted the video to Facebook, Breazeale was quick to comment: "I'm the one in the video Kyle!! You absolutely made my life! I couldn't have asked for anything better to happen to me!! I am your absolute biggest fan and always will be! It was amazing to see you win twice this weekend!!! Absolutely amazing!!"
He even later responds: "Safe travels, email when u can."
