Charlize Theron has apparently been warned.

According to a report by Radar, friends of the South African beauty, and mother to two-year-old Jackson, are sharing their fears that the actress may make the biggest mistake of her life if she chooses to marry boyfriend Sean Penn.

“They’re urging her to think twice before finally heading down the aisle with Sean,” said a source, claiming her friends believe her life may be in danger if she goes through with a wedding.

It could be argued that the 38-year-old’s friends my have a valid point based on Penn’s past.

The 53-year-old Milk star was charged with domestic assault in 1987 after he allegedly hit then-wife Madonna with a baseball bat. He was also sentenced to 60 days jail time for punching a movie extra while filming the 1988 film, Colors.

“They fear for her safety,” said the source.

There has been much speculation over whether the couple of more than seven months will be walking down the aisle any time soon.

“The two began talking about marriage in the last few weeks, after Sean moved into Charlize’s house,” a source told Radar in February. “She has never wanted to get married, but seeing how Sean interacts with Jackson, she is having a change of heart.”

It’s not likely Theron will listen to any advice her friends may — or may not — have given. She seems thoroughly happy with her new man.

“It just kind of naturally happened, and before I knew it, I was in something that was making my life better—the people who really love me can see the effect it has had on me,” Theron recently said of the relationship to Vogue.
