The Dallas Buyers Club actor has making the same faces for the past several months, and his Instagram is proof positive that the pose is his new favorite go-to move.
It seems that Leto tends to make a shocked face in a lot of candid photos lately.
In one pic on the star's photo sharing page, he posted a shot of himself from the SAG Awards.
Leto is shown with his mouth wide open as he proudly clutches the coveted trophy.
Another photo shows him posing with Zedd (and making the same adorbs face, of course) during Grammy night.
"Me eating grammy winners @Zedd's face. Congrats brother!" he wrote as a caption.
Leto even took his shocked face to the Los Angeles premiere of his hit film.
He shared an image of himself on the red carpet and wrote on the Instagram, " Flashback Friday: Me at the #DallasBuyersClub LA Premiere."
Next up is an adorable picture of him posting with his brother Shannon at the Golden Globe Awards.
The 42-year-old clutched the golden statue while embracing his older brother.
And last, but certainly not least, is a snapshot showing Leto getting up close and personal with some fans of his band, 30 Seconds to Mars.
"With some friends in Richmond, Virginia last week…LoveLustFaithDreamsTour," he posted.
Between the perfect hair (ugh) and the adorable expressions, it's hard not to love Leto, isn't it?
