Emma Watson and bodyguard (Pinterest @Maria Schroeder)

“Harry Potter” and “The Perks of Being a Wallflower” star Emma Watson was recently seen at her graduation sitting with her fellow graduates. Her body guard accompanied her and her family to the event, blending in with the class of 2014 by wearing a graduation cap and gown. 

Security for celebs means two things: safety and privacy. 

Here are some celebs that like to keep their lives private, even though they are always under the radar.

1. While Emma Watson's graduation was not kept a secret, her security was with her at all times, both during the ceremony and walking with her 

2. Emma Stone and Andrew Garfield:

Despite the fact that everyone knows that they are a couple, the two have never admitted to it. In interviews with BBC and others, Andrew Garfield has worked around questions and comments about his off screen life, keeping his relationship protected and private. Emma Stone does the same. 

3. Kristen Bell and Dax Shepard:

Though the comedic pair is vocal about their love for each other, their daughter and dogs, Bell and Shepard are strict when it comes to their daughter Lincoln being photographed out in public. Bell urged E! News and other organizations to support her action to stop paparazzi from taking photos of celebrity children.

The couple is often seen with their children and captured on camera, but like Kristen and Dax Shepard, they are also against their children being exposed to the public and media. Garner gave a testimony in front of the Assembly Judiciary Committee at the California State Capitol. “…I don’t want a gang of shouting, arguing, law-breaking photographers, who camp put everywhere we are, every day, to continue traumatizing my kids,” she said, according to Variety. 

5. Halle Berry:

Like Jennifer Garner, Berry adds that she is a mother of “little innocent children who didn’t ask to be celebrities.”

Perhaps described at Hollywood’s favorite couple, Jolie and Pitt do a good job at keeping their private lives a secret. Everyone is still wondering when their wedding will be and the guessing and waiting will probably continue. On the other hand, the two are vocal about on screen experiences—but that’s not really private, is it?

7. Beyoncé and Jay-Z:

The musical couple perform and tour together, but keep their home and work lives in check. Beyoncé told Piers Morgan on his former CNN show that her persona on stage and at home are two different things.
