Robert Pattinson - Robert Pattinson's family Thanksgiving with Kristen

Robert Pattinson's family Thanksgiving with Kristen

Robert Pattinson and Kristen Stewart spent Thanksgiving (22.11.12) in London with his family.

The low-key couple were spotted checking in at Heathrow airport on Friday (23.11.12) for a flight to New York where they happily queued up with other passengers before taking their seats in first class.

One excited fan tweeted:''Look who's on my plane!!! Robert Pattinson and Kristen Stewart!! We just arrived at the same time they were behind me in the line!''

The trip to London comes after it was revealed 26-year-old Robert's older sisters Lizzy and Victoria have finally forgiven Kristen, 22, for cheating on their brother with married director Rupert Sanders.

A source said: ''It was really important for Kristen to win back the love and trust of Rob's family, and she has done just that.

''They are all back on really good terms -- even better than before. Kristen reached out to Rob's sisters and expressed how sorry she was. They are proud of how far she has come and they know she has been treating their brother like gold.''
