My name is Grant Gustin and I'm the best singer alive.

who else was smiling during the whole video❤

This proves there's no autotune in the song

"My name is Barry Allen, and I'm the best singer alive"

I loved how he blushed every time someone complimented him

Everytime someone says "I love you" he smiles and tries not to laugh. He smile is the cutest one i have ever seen

The fact that his live singing is just as perfect as the actual episode gives me chills 😭

I love how his voice sounds exactly like the recording it’s beautiful

HIS SMILE IS SO CUTE

Dont care what anyone says, this man is and always will be the one true Flash

Grant Gustin:

People: RUN BARRY RUN

Who else is here from 2024? I love this song.

He protecc,

All of the wells:SING BARRY SING!

"I'm The Flashhh".🥴🥴🥴

I love that he smiles every time someone yells "I Love You." He's so sweet🥰😂

This is how many people watch the flash

Imagine his wife everyday waking up to perfection

When Barry Allen isn’t messing up timelines and saving the day, he makes beautiful albums and go sing in concerts.
