Emma Watson has moved her new boyfriend Johnny Simmons into her dad's house. The pair have been dating since they met on the sets of their new movie "The Perks of Being a Wall Flower" this year.

A source explained: "Things are getting pretty serious between Emma and Johnny so she wanted to take him back to London to meet her parents. They've been having a brilliant time together. Emma knows the city like the back of her hand so is a great person to show him around."

"They've been taking bikes or eco-cars to every tourist trap in the capital, including the London Eye, Big Ben and St. Paul's Cathedral."
