Kristen Stewart and Robert Pattinson are locked in an emotional dogfight over their pet pooch.
They adopted their mutt, Bear, from a Louisiana animal shelter while they were filming a “Twilight” flick.
“After Rob moved his things out of their Los Angeles home, he then told Kristen he wanted Bear,” a source close to the couple told Radar Online.
“She wants joint custody, and it could get a little messy,” the source said.
Meanwhile, Pattinson has dropped out of an upcoming US press appearance for his new film, “Cosmopolis,” Entertainment Tonight reported.
