Some stars are never completely comfortable shooting sex scenes. But the thought of their parents watching them romp onscreen makes some actresses -- and actors -- downright squeamish.
Amanda Seyfried, Sienna Miller and Eva Mendes have all tried to shield their parents, especially dads, from watching their more intimate scenes. Even some actors, such as "Harry Potter" star Rupert Grint, have called the experience nerve-wracking.
As for the parents, the experience of seeing their sons and daughters nude (or nearly nude) on screen can be equally disturbing.
It's no surprise then that Oscar-nominated actor Laurence Fishburne is upset by his daughter Montana's decision to appear in a porn video. Nor is it likely that star of "The Matrix," "What's Love Got to Do With It" and "CSI" will be watching his daughter's small screen debut next week.
The 19-year-old, who will star in a hardcore pornographic video with the tagline "An A-List Daughter Makes her XXX Debut" has admitted that her father is "very upset."
"I heard that he's mad at me, but I haven't spoken to him yet," she told TMZ earlier this week. "I feel pretty confident that I can work things out with him. I think he wants to support me in everything I do, and though he sees this now as a negative, I believe in time he will view it as a positive."
According to TMZ, the actor's friends tried to block the video's release by buying up all the DVDs. Fishburne's rep declined to comment.
Montana, who has said she is eager to break into Hollywood and become a star like dad, claims she is taking a page from Kim Kardashian's playbook.
"I've watched how successful Kim Kardashian became and I think a lot of it was due to the release of her sex tape," Montana said in a statement through Vivid Entertainment, which will release her tape Aug. 10. "I'm hoping the same magic will work for me. I'm impatient about getting well-known and having more opportunities and this seemed like a great way to get started on it."
Vivid also distributed Kardashian and Kendra Wilkinson's sex tape -- but in both those cases, the celebrities claimed their tape was obtained illegally. Vivid claims Montana approached them about making her own porn.
Some are questioning Montana's chosen path to stardom. Why not follow in the footsteps of her father, who gained notoriety with a small role in "Apocolypse Now" and worked his way toward critical success on the big and small screen and Broadway?
Bonnie Fuller, editor-in-chief of Hollywood Life is calling on Kardashian to speak out. "I think that Kim as a role model has a duty to speak out here and say this isn't a valid career choice," Fuller told Fox411.com.
While mainstream stars are hardly doing porn, they still find the idea of their parents watching them act in their own racy scenes unsettling. Below are some of the stars who have banned their parents, especially dads, from seeing their on-screen romps as well as a couple stars who don't seem to mind.
