Watch out the next time you want to go through your significant other's phone looking for photos of them cheating, you might get more than you bargained for.

According to Grimsby Telegraph, a woman in Louth, Lincolnshire, England went snooping through her boyfriend's old phone and it's not clear if she was looking for signs of him cheating or not, but she was definitely not prepared for what she saw.

She found photos of her 19-year-old boyfriend, Wayne Bryson, having sex with her dog.

He had taken the photos of his sexual encounter with her Staffordshire bull terrier last month and forgot to delete them.

She called police and Bryson was arrested for having sex with an animal and also for the drugs police found on him when he was arrested.

He is looking at a maximum of two years in prison for the charges.
