Amber Heard responds to Johnny Depp's claim that she soiled their bed

The back and forth between exes Johnny Depp and Amber Heard continues with the actor accusing his ex-wife of committing a disgusting act out of revenge.

Just last week, Depp accused Heard of "punching him twice in the face," allegations she called "totally false." And now Heard's been forced to deny new allegations from the actor that she defecated on their marital bed on that same night.

According to Depp, both incidents occurred after Heard's 30th birthday party on April 21, 2016. He said that because he was two hours late to the celebrations, Heard allegedly left faeces on their bed as payback -- and he claims to have photos to proof it.

"[There is] strong, photographic evidence that connected Amber to the faeces," a source told The Mirror, adding that the faecal matter was left their as a "prank."

However, Depp didn't see the funny side and when he found the poo between the sheets, and it sparked a major argument between the pair. He eventually stormed out of their LA penthouse and subsequently put an end to their marriage.

Today Heard hit back at her ex's latest claim, saying through her lawyer that the faeces was from their Yorkshire terrier, Boo. The couple have another dog, Pistol -- the two dogs made headlines of their own a couple of years ago when Depp and Heard smuggled them into Australia without filling out the appropriate paperwork, and then-Agriculture Minister Barnaby Joyce threatened to have the dogs put down if they weren't sent back to California.

"Boo has some serious bowel control issues. There was never a joke, it wasn't something done to be disrespectful," said Heard's rep. "It was an innocent thing, it's what pets will do. We don't have anything else to say. Ms Heard is moving on and we do not want to engage in this nonsense."

But according to The Mail, a housekeeper found the soiled sheets the next day and concluded that the faeces were too big to be from a dog.
