Cameron Diaz is planning to marry Paul Sculfor

The couple, who have been dating since last May, have reportedly decided to take their relationship to the next level after the British model recently moved into Cameron's Los Angeles home.

A source said: "Cameron and Paul are having a wonderful time and don't want to spoil it by pushing things, but they have used the m-word occasionally.

"They're playing house in a serious way - both openly admit marriage scares them but they are very much in love and the subject has come up."

The "Charlie's Angels" star and her lover - who has previously dated Jennifer Aniston and model Lisa Snowdon - have met each other's friends and families and are now planning more family get-togethers as their romance grows increasingly serious.

The source added: "They have plans for another round of family meetings in the near future and the betting is that a proposal is imminent.

"This relationship is something very special and they are both taking it very seriously indeed."
