While Twilight star Robert Pattinson joined co-star Taylor Lautner in Berlin this weekend for the Breaking Dawn Part One premiere, female lead Kristen Stewart remained in London for filming.

Kristen Stewart has been going back and forth between the set of her new show, Snow White and the Huntsman, and Pattinson's parents' house in London, where she has been staying. The starlet is reportedly "glum" without her boyfriend Rob by her side after the two were inseparable this past week while promoting the debut of Breaking Dawn Part One.

Breaking Dawn Part One debuted in 3,521 locations on Friday morning at midnight. The midnight screenings alone have brought in an estimated $30.25 million.

Many are excited to see the fourth movie in the five part film saga based on Stephanie Meyer's infamous Twilight series because of the highly anticipated sex scene with Stewart's and Pattinson's characters, Bella and Edward.

'It's crazy how close they are," director Bill Codon says of Stewart and Pattinson's unquestionable chemistry between the real life couple. "Because obviously, this is the part where they are together, and that's something they didn't have to act."

The final movie, Breaking Dawn Part Two, is scheduled to premiere in one year from now.
