The two are rumored to be dating and Robert popped the question.
“He asked me to marry him,” Kristen, 20, told Britain’s News of The World newspaper.
“As a joke, though. Well, at least I think so!”
On the other hand, Rob, 23, recently revealed he has a “special bond” with Kristen.
“Kristen and I have a special bond together, she is the sweetest, smartest and strongest girl I know,” he said during a magazine interview. “If we have a relationship I would rather not say, because my words get twisted around too much and can be ‘old news’ by the time this interview is printed.
“I’ve been linked to a lot of actresses in Hollywood, most of them I find too silly and shallow that I would not want to date them.”
