Milo Ventimiglia is best known for his role as Jack Pearson in This Is Us (2016-2022) and many other projects.

Aside from his professional work, he is also known for his crooked mouth.

The actor has talked about his crooked mouth on multiple occasions throughout the years.

He has also shared several stories about it, including how it posed a big problem for him when he was starting out in his career.

Ventimiglia spent years practicing reading a book in front of a mirror to make his crooked mouth unnoticeable.

"Every time I'd catch myself getting this slanted, really pronounced mouth, I would figure out a way to straighten the word out," he told People.

He also added that while he had straightened his jaw while speaking, it would still pop out while running and yelling.

"If I'm running and yelling in a scene, I can't control it. It gets so crooked!"

How Milo Ventimiglia Found Out about His Crooked Mouth

Ventimiglia opened up about discovering he had crooked lips when talking to Drew Barrymore.

The actor shared that he only noticed how slanted his lip was when he watched an interview of himself during a wrestling tournament on TV.

"At 11 O'clock at night, when the Orange county news channel is on, I'm like, 'Oh man. I'm gonna be on TV. This is gonna be amazing,'" he recounted.

"I'm watching this and the only thing I can focus on is this really, really severely crooked mouth. And I turn to my mom and I'm like, 'Mom, is that really what I look like?'"

Ventimiglia noted he was very aware of his slanted lips from that point on. In hindsight, he said it wasn't all that bad, especially since it had become somewhat of his signature.

It also helped him land a job with Sylvester Stallone on Creed II (2018).

Stallone is also famous for his crooked smile, which he got from facial paralysis resulting from birth complications.

As for Ventimiglia, his crooked lips resulted from being born with dead nerves in his lips.
