Twilight superstar Robert Pattinson's rumoured girlfriend, Dylan Penn (daughter of Sean Penn and Robin Wright) is apparently afraid to get serious with him.
"She doesn't want to be known as Rob's girlfriend. She's afraid to get serious with him and lose her privacy," a source told Us Magazine.
Pattinson, meanwhile, is also reportedly taking things slow after Kristen Stewart.
"Rob isn't ready to be exclusive with anyone right now. He's just enjoying himself," sources stated.
Pattinson and Stewart split up for the second time after she got back in touch with Snow White and the Huntsman director Rupert Sanders.
Meanwhile, Dylan's dad has reportedly warned Pattinson that he doesn't mess around with his daughter. Sean has told Pattinson not to get too heavy with Dylan if he's not looking for a serious relationship because he doesn't want to see her getting hurt.
"Rob and Dylan get on well and really fancy one another. It's obvious Dylan is smitten. But Sean had a chat with Rob recently. Sean knows what it's like to be a young, successful actor and the beautiful women that come with it," a source told The Sun.

Sources present at The Viper Room stated that they even left the hotel together to grab a bite at the Chateau Marmont Hotel and then headed straight to Pattinson's house.
"They went into his kitchen, and he put his arms around her. Then he was kissing her neck and talking all lovey-dovey. It was clear they'd been out together before," the source added.
