The Titanic star has decided to spend some time alone after splitting from the 35-year-old, the Mail on Sunday reported. She started dating him just months after separating from husband Sam Mendes in March.
A close friend told the newspaper: 'Louis was just the tonic Kate needed after her painful split from Sam and they had a wonderful time. However, they have realised their relationship isn’t working and Kate needs space to be on her own. She is very grateful to Louis for helping her pick her life back up after her marriage ended and they had a lot of fun together, but she felt it had come to an end and wants to concentrate on her career and children.'
