Is Twilight actor Robert Pattinson splitting up with sweetheart Kristen Stewart? The two are reportedly going separate ways, at least for the holidays.

Pattinson will head back to his native London to spend the Yuletide season with his family while his on-and-off screen partner Kristen will spend the holidays in Los Angeles. The two will be taking a break from filming Breaking Dawn Part 1.

"Rob's heading home to London to be with his friends and family while Kristen is going back to Los Angeles," a source tells Showbizspy.com.

"Rob and Kristen won't be spending Christmas together."

But it's not that something is wrong with their relationship. In fact, reports say that Pattinson and Stewart are going strong when it comes to their romance. Rumours that the two actors are getting sick of each other have been rendered false by more credible sources after it circulated in cyberspace.

Filming for Breaking Dawn is business as usual, reports a source quoted by entertainment outlet E! The same source says that the filming for the fourth instalment in the Twilight Saga will be the best film yet and filming had gone smoothly so far. Pattinson and Kristen had already finished filming their honeymoon sequence set in Brazil.
