Robert Pattinson and Kristen Stewart
Kristen has previously expressed what boyfriend Rob means to her: back in 2010, she said: 'Rob is sexy, in a tortured artist way. This might be because he is British. He's tall, looks like he is thinking all the time and is incredibly funny.'
Rob, too, has admitted that Kristen means something special to him.
'There's definitely, I don't know chemistry, or whatever but I definitely had some kind of change, I felt something with Kristen,' he gushed.
