Check Out the Most Surprising Celeb Transformations of the Week

We love this transformation. 

The Jane the Virgin alum chopped off his long hair to donate to Locks of Love on April 15. Justin took to Instagram to document the process, revealing the moment was four years in the making. In the video, the star and director of the upcoming big-screen adaptation of Colleen Hoover‘s It Ends With Us explained his decision to his 5-year-old son Maxwell Roland-Samuel, who then uses a pair of scissors to chop off the first locks of Justin’s hair (while being supervised by a hairstylist).

“The reason they’re cutting it like that, baby,” Justin said, “is ’cause Daddy’s gonna donate his hair to somebody who can’t grow their hair ’cause maybe they got cancer like Uncle Zach, or they lost their hair.” He then continued, “So he’s gonna give all this hair to somebody.” After Maxwell cut off a ponytail, Justin held it up to his son and said, “Someone’s gonna be so happy to have this hair.” 

Several days later, Justin shared a photo of his shorter ‘do, offering a glimpse into his prep to play fan-favorite Ryle in It Ends With Us opposite Blake Lively as Lily. 

“A lot of change in one week,” Justin captioned a April 17 gym selfie. “Cut my hair. Started eating carbs. And now I’m seeking validation from strangers on the internet by posting thirst traps. Wait …is this a thirst trap? Just Googled it. Don’t google thirst trap.”
