Matt Smith and Lily James have moved in together.

A source told the Sun on Sunday: "They are head over heels and both think they have found the one. Lily moved into Matt’s London home and there’s been no arguing over who’s hogging the bathroom cupboards – yet."

Meanwhile, Lily, 27, previously revealed she loved working with Matt, 33, on comedy horror movie 'Pride and Prejudice and Zombies'.

She said: "He just made me laugh all the time. I actually loved being able to talk about work. It was great that he had to propose to me [in the movie]."

Lily also admitted she was initially reluctant to join the Burr Steers-directed movie, but was convinced after reading the script.

She said: "When I saw the e-mail from my agent, I was like, 'This sounds terrible!' Then within 20 pages of the script, I thought, 'This is so cool! Somehow these two worlds join together, and it's a riot.'"
