Rumours claimed that British actor Robert Pattinson is planning to ask Kristen Stewart's hand for marriage before he is set to fly to Australia for his next project.

This is backed by the rumor that Rob is reportedly plotting, planning and designing the perfect ring for Kristen's finger.

Rob seemed to be planning a romantic proposal for his girlfriend that contradicts the on-going rumours that the Twilight couple is already planning their wedding supported by reports saying that Kristen is shopping for a vintage wedding dress and Rob writing a wedding song.

Over the weekend, the pair had a Christmas tree decorating party in advance of the holiday season. HollywoodLife.com quoted a source close to Stewart who shed some details on their 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," the source said.

With Rob set to invade Australia in January for filming of "The Rover", the two seem content to enjoy as much time together as possible before he leaves.

"Kristen was really happy to be back home and be with Rob," stated the friend. "They want to spend as much time as possible together before Rob leaves in January to film his next movie."

According to E! News, Pattinson's exact departure date is Jan. 8, leaving enough time for him and Stewart to enjoy Christmas and New Year's together.

"For them, the holidays means just hanging out at the house with close friends and Bear and Bernie and just being super mellow," their friend added.

The Twilight couple has been dating for almost three years since they met in the set of the Twilight Saga. But the relationship went rocky when it was revealed the brunette cheated on him with married "Snow White and the Huntsman" director Rupert Sanders last summer.

Robert Pattinson and Kristen Stewart have not yet commented on the swirling rumors about their relationship.
