Now, we all know Mark Wahlberg.
Also known as Marky Mark, he's one of America's best known actors.
He was born in 1971 in Boston, Massachusetts.
And actually rose to fame as a rapper with Marky Mark and the Funky Bunch.
He made the transition into acting in 1994.
With his first movie role in Renaissance Man.
His first starring role soon followed in Fear in 1996.
But he really rose to prominence with his role in 1997's Boogie Nights.
He followed this success with roles in many action movies, including The Perfect Storm (2000), Planet of the Apes (2001), and The Italian Job (2003).
He is also known for comedic roles in Ted (2012) and Daddy's Home (2015).
In fact, believe it or not, he was the highest-paid actor in the world in 2017.
Quite an impressive accolade!
Alongside acting, Wahlberg is a producer and businessman.
And he received a star on the Hollywood Walk Of Fame back in 2010.
There's no denying he's had an extremely successful professional life.
But behind the scenes, things haven't always been so seemingly perfect ...
In fact, Wahlberg is certainly no stranger to controversy.
As a teenager, Wahlberg, who comes from a family of 9 siblings, dropped out of high school and quickly became embroiled in a life of crime.
By the age of thirteen, he was addicted to drugs.
Wahlberg got himself involved in drug dealing, stealing, and all-around violent behavior which would eventually lead to him serving time in prison at the age of sixteen.
But, after he was released from prison...
Wahlberg realized it was time to turn his life around and put his troubles behind him.
The actor has briefly touched upon his crimes over the years...
Speaking to Associated Press in 2014 of his actions, he said:
"I have apologized, many times. The first opportunity I had to apologize was right there in court when all the dust had settled and I was getting shackled and taken away, and making sure I paid my debt to society and continue to try and do things that make up for the mistakes that I've made."
Despite his troubled past, Wahlberg has gone from strength to strength in his career.
And it's showing no signs of slowing down...
Wahlberg has landed a new role in an upcoming movie, Father Stu.
And it's safe to say, he's been putting in the work to get into character.
Wahlberg has been putting on "as much weight as possible" for his new role.
In an interview on Jimmy Kimmel Live!, Wahlberg opened up about how he planned to prepare for the role.
"After we do the boxing scenes, I get to put on as much weight as possible over the course of the film, so I'm challenging myself to put on 30 pounds in the next six weeks," he said.
"They want me to do it as healthy as possible. I'm like, 'Dude, I've been on such a regimen for so long, I just want to eat everything in sight.' I want to go to bakeries, I want to go to Denny's, I want to get pancakes. I want to get everything that I could possibly get my hands on."
And now, he's shared a three week before and after picture on Instagram, people are stunned...
