Fine art by celebrities -- 9 who should just put down that paintbrushRecently, when we found out that Marilyn Manson paints (characters from "Lost," to boot!), we started to wonder ...

What other celebs moonlight as behind-the-scenes Picassos? Once we did a little digging, we found that quite a few other stars have an artistic bent, but perhaps a few should stick to their day jobs and, shall we say, back away from the paintbrush?

From Brad Pitt and Pierce Brosnan, to Rosie O'Donnell and Marilyn Monroe, click below to see some of the "finest" art by A-listers we found ...

8. James Franco

James Franco seems to be young at heart. The Green Goblin's son apparently likes to paint while wearing a Spider-Man sweatshirt. Well, no offense, but this piece on canvas (from a gallery exhibition that the actor had back in 2006) kind of reminds me of my geometry notebook at the end of my sophomore year of high school.

7. Rosie O'Donnell

Rosie isn't just outspoken on TV and in the blogosphere. She also takes to canvas to make her voice heard. She calls this one "The View." Given that the right eye looks like it was bandaged from being punched out, we wonder if Rosie had Elisabeth Hasselbeck in mind for this one.

6. Jeff Bridges

The "Crazy Heart" actor does double duty in front of and behind the camera on many of his flicks, creating photo diaries on his personal website, which is also replete with movie-related and random sketches, like this one inspired by "Tron." Props to the actor for having an eye for Oscar-winning scripts and art alike.

5. Pete Wentz & "Travie" McCoy

Ashley Simpson's baby daddy and Katy Perry's ex (also lead singer of Gym Class Heroes) teamed up to do a collaborative art show. The guys said that the mixed media and graffiti-inspired artwork was "fueled by a mixed drink of Merlot and Sprite." So that explains the blue-Ewok-meets–Easter Bunny character here. Yep, we totally get it.

4. Pierce Brosnan

The former 007 was trained as a commercial artist in South London. Here, he paints himself as a character on
"The Simpsons."

3. Brad Pitt

When he's not toting his brood around the globe or producing three movies at a time or cheering on the New Orleans Saints, Brad Pitt takes photographs. He even had a collection of snaps published in W magazine a couple years back. Surveys show that 97 percent of Americans would feel inspired if their personal muse was Angelina Jolie eating a burger. (Look, she eats!)

2. Viggo Mortensen

The "Lord of the Rings" actor writes poetry, takes photographs and paints abstract art. But mostly we just love when he speaks Elvish.

1. Marilyn Monroe

The legendary movie star painted this watercolor of a red rose, which was inscribed to President John F. Kennedy for his birthday. Although it must have sucked to be Jackie, this is eerily romantic.
