Robert Pattinson had a word with girlfriend's dad Sean Penn

 Robert Pattinson, who is dating model Dylan Penn, had a one-on-one chat with his girlfriend's father and actor Sean Penn.

Penn met Pattinson to make sure his daughter doesn't get hurt, reports showbizspy.com.

"Rob and Dylan get on well and really fancy one another. It's obvious Dylan is smitten," a source told Britain's Metro newspaper.

"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. Sean gave his piece about not getting too heavy with his daughter if he's playing the field, as he doesn't want to see her hurt," the source added.
