The 'Suicide Squad' actress turns 24 on August 13, but celebrated with her friends at close pal Suki Waterhouse's London home on Friday (05.08.16) night, with a night of raunchy entertainment.

The lavish party was reportedly laid on by London nightclub Mahiki, while nearby venue The Box planned the entertainment.

Photos showed naked dancers walking around the event before they put on a show for the guests, while a picture Suki shared on Instagram featured Cara, with her face covered in cream, in front of a giant cake, which had a topless girl jumping out of it.

Suki simply captioned the picture: "Bosh".

Guests at the party included Cara's sister, Poppy Delevingne, her 'Suicide Squad' co-stars Margot Robbie - who arrived clutching a pineapple - and Karen Fukuhara, and singer Ed Sheeran.

Meanwhile, Cara - who is dating St. Vincent aka Annie Clarke - has sparked outrage after her beloved dog Leo was spotted wearing a 'pepper spray' training collar to stop him from barking.

The 23-year-old beauty was seen leaving Claridge's Hotel in London with the husky crossbreed, with the device - which gives off a spray of citronella when the animal reaches a certain decibel level - clearly visible around his neck.

Lynn Barber, the training and behaviour manager for Dogs Trust charity, told the Mail Online website: "At the Dogs Trust we don't recommend the use of any adverse technique or equipment for any kind of behaviour issue.

"You have to find out the cause of the dog's behaviour rather than punish it."
