Paris Hilton has hung life-sized pictures of herself in her boyfriend's house.

A source said: "Before jet-setting to Vancouver, Paris had her team pay a visit to Doug's house, bringing over life-size photos of herself to hang throughout the mansion."

Paris - who failed to ask her lover's permission before making changes to his home - also hung several framed photographs of the couple on the walls of the property.

The source added to E! Online: "Seriously, there were only a few photos that survived Paris' redecorating."

Paris and Doug recently returned from a romantic holiday to Wadigi Island in Fiji after 'The Hills' star decided to surprise his lover in a bid to win her back.

A source said: "He has been so generous and sweet, and has really impressed her with his romantic ways. She loves being treated like a princess... she can feel how deeply in love he is with her, and she's having a blast."
