Megan Fox has "outgrown" her tattoo.

The 25-year-old actress had a tattoo of Hollywood icon Marilyn Monroe inked onto her right arm when she was a teenager. Nearly a decade later, Megan is finding the action regrettable.

She simply is no longer impressed by the artwork.

"I'm just over it," Megan told People magazine after her performance in Montblanc's 24-Hour Plays in New York City this week.

"You outgrow things that you love when you were a child. I got it when I was 18 and now I'm 25 and it just doesn't make sense anymore."

Removing the tattoo is an arduous process for the star. Megan will undergo numerous treatments to lift the ink from her skin.

"The removal process is a hundred times worse than the tattoo itself," she revealed. "I've only done one session so I probably have three or four left."

Megan has other tattoos on her body which she will keep intact, including a Shakespearean reference on her shoulder and her husband Brian Austin Green's name in calligraphy on her hip.

The actress believes that getting Marilyn Monroe off of her body will be extremely successful.

"I think it will come off completely because I have the right skin type to remove ink. The more fair skinned you are the easier it is to remove dark ink, and I'm as fair as it gets."

Megan's upcoming film Friends With Kids is slated for release in April 2012.
