Kristen Stewart and Robert Pattinson at war over their dog
Just days after it was revealed that Kristen had cheated on her boyfriend, it's reported that the pair are embroiled in a bitter custody battle over their dog, Bear.
Rob, 26, left the LA home he shared with Kristen this weekend and is said to be denying Kristen, 22, access to their pet.
A source told RadarOnline: "After Rob moved his things out of their Los Angeles apartment, he then told Kristen he wanted Bear.
"She was heartbroken - they adopted Bear together and she always felt that he was their little baby.
"But Rob was so hurt by Kristen's actions he decided that he wants the dog to help him get over what happened. After all, a dog is a man's best friend and Bear is such a good companion."
The couple adopted Bear together from a shelter in New Orleans, but Rob is said to be "so hurt" by Kristen's actions that he wants the pooch to help him get over his heartbreak.
Kristen - who last week issued a public apology for her "affair" with her married Snow White And The Huntsman director Rupert Sanders, 41 - wants joint custody.
The source added: "It could get a little messy."
