According to FemaleFirst, the actress is hoping that the purchase of the new house will solidify their relationship, after having been separated recently because of their busy schedules.
Knightley is also concerned about Friend’s relationship with his co-star, Sophia Myles, in the film Buddha’s Little Finger.
The actress’s friend commented, "They have been arguing about Rupert’s workload and how little time they spend together. Keira was quite concerned they were drifting apart and was also worried he was getting a bit too close to Sophia. So she flew to the set in Germany and they sorted things out. It was then that they decided to buy a house together and they are going to put in £1 million each."
