LONDON: Actress Kristen Stewart and ex-boyfriend Robert Pattinson are reportedly involved in a custody battle over their adopted dog.

“Pattinson is determined to take the dog and this doesn’t sit well with Stewart at all as she has spent a lot of her time with the rescued hound. She also took care of the pet when he was a pup suffering from the potentially fatal Parvo disease,” reported contactmusic.com.

The estranged couple are said to be no longer on speaking terms for the time being and have been living apart ever since the photos of actress and her “Snow and the Huntsman” director Rupert Sanders were published.
