The couple invited friends and family to Kristen's Los Feliz home for a festive party. "Kristen and Rob had a small, intimate Christmas tree decorating party on Sunday. They have a gorgeous tree set up at Kristen's where Rob pretty much lives now," showbizspy.com quoted a source as saying.

"Kristen was really happy to be back home and be with Rob. They want to spend as much time as possible together before Rob leaves in January to film his next movie," added the source.  Meanwhile, it has been claimed that Pattinson, 26, hates the fact that Stewart has bad body odour.

"Rob's a laid-back guy, but he is starting to find Kristen's grungy habits a turnoff. She rarely washes her hair, only brushes her teeth once a day at best and very rarely wears perfume," the source said.
