MUMBAI: Patrick Schwarzenegger is reportedly so mortified by his singer girlfriend Miley Cyrus' unkept house that he avoids spending time there.

According to a source, Schwarzenegger is smitten with the 22-year-old, but is put off by her habits of dropping cigarette ash on her furniture and allowing her pets to go to the toilet wherever they want, reports contactmusic.com.

"Patrick went to her house after they partied on Halloween, but he's not spending much time there," Heat magazine quoted the source as saying.

"There was dog poop everywhere and her once-white couch is covered in burn marks and unidentifiable stains," the source added.
