Pop singer Ariana Grande has still not forgiven P&O Ferries for refusing to let her dogs travel between France and Dover.

The singer, her mum Joan and half-brother Frankie were travelling on a cross-Channel ferry last year when staff refused to let them take their two dogs Toulouse and Sirius on the Dover-bound journey because they did not have the right paperwork.

Ariana is still seething about the incident, as she told a national newspaper.

“P&O never apologised.” She said. “That was a rough experience. My dogs are my life, I love my dogs, my babies. I saw it happen in front of my eyes, so any corporation that threatens my dogs’ lives is never going to be okay in my book.”

Her mother Joan recalled the drama on Twitter, describing it as “that time Ariana Grande’s dogs were almost murdered.”

Half-brother Frankie stayed in France to get the paperwork for the dogs so that the singer and her mum could travel to England for her UK tour.

At the time, Ariana tweeted: “This was unacceptable.”

Her mum also vented on Twitter, she said: “My experience crossing from Calais, France, to Dover, UK, on the ferry was the worst experience of my life.

“The P&O ferry was lovely, just to set things straight, the people at the ferry border were horrible to me and to Toulouse and Sirius.

“The problem was in Calais. All the dog paperwork was correct, but they refused entry to Toulouse and Sirius because, why? Nothing.

“I’m telling the story because abusive people shouldn’t be in power and we must stand together, when we see bullying and abuse, and make it stop.”

Her daughter Ariana was thrust into the spotlight when she appeared on Broadway, sparking other appearances on Nickelodeon TV programmes.

A press spokesman for P&O said: “Unfortunately, from time to time pet owners arrive at Calais with animals that don’t meet Defra’s requirements for entry into the UK.

“This is invariably hugely frustrating for the pet owner who has to decide whether to travel without the pets or to visit a vet in France to put matters in order.

“We had some difficulty in explaining the situation but eventually our supervisor gave the travelling companions a lift back to the ferry terminal with the pets, explained what would need to be done, and provided details of the nearest vet so arrangements could be made for the animals to be properly certified for travel at a later date.”
