Watch: Mark Wahlberg Kept that Prosthetic Penis from 'Boogie Nights'

Promoting his new film "Father Stu," Mark Wahlberg stopped by "The Ellen DeGeneres Show" on Wednesday and recalled a less-than-PG role from his past – that of adult star Dirk Diggler in Paul Thomas Anderson's "Boogie Nights."

Set in the 1970s, it tells of Diggler's rise-to-porn-fame due to his excessively large penis.

"Throughout the film it's inferred several times that he has a massive penis, when it's finally showed in the final shot of the film," writes the Daily Mail. When the film was released, Wahlberg admitted it was a prosthetic.

Ellen asked the 50-year-old actor as to the whereabouts of the prosthetic, to which the Oscar-nominated actor said he still has it, but keeps it in a secure place.

"Yes. It's in a safe, locked away. It's not something I can leave out. All of the sudden my kids are looking for the spare phone charger and pull that thing out," he joked.

He added it, "wouldn't be a good look" if his kids found it, and when Ellen asked if any of his four children he shares with wife Rhea -�18-year-old Ella, 16-year-old Michael, 13-year-old Brendan and 12-year-old Grace - have seen the movie, he added he thinks his daughter Ella has.

"I think my daughter has, but she has not had the conversation with me, thank God. She's sparing me," Wahlberg said.

"The actor has joked in the past that he was planning on selling the prop at a charity auction," reported Page Six.

The 1997 movie was a turning point for Wahlberg, who was transitioning away from his music and underwear-model career.

Ellen also complimented him for his performance, along with chiding him by saying: "Who would have thought Marky Mark would turn into a brilliant actor."
"Nobody would have thought. That's why the expectations were so low when I started acting that it was just like, you do something remotely interesting, 'Oh my God, he's fantastic!;" Wahlberg told Ellen.

"The next thing you know they're nominating me for an Oscar," he added, with Wahlberg's first nomination coming in 2006 with "The Departed." His second came in 2010 when "The Fighter" was nominated for Best Picture. He was a producer on the film.

But don't expect Wahlberg to be dangling his privates in public any time soon after making the inspirational "Father Stu" (in theaters).

"I feel like this is starting a new chapter for me in that, now, doing things like this -- real substance -- can help people," he told Entertainment Weekly. "I definitely want to focus on making more. I wouldn't say necessarily just faith-based content but things that will help people. So, hopefully this movie will open a door for not only myself but for lots of other people in Hollywood to make more meaningful content."
