Cara Delevingne's paparazzi nightmare after ex Michelle hooks up with Zac Efron

British supermodel Cara Delevingne has shared shocking footage of the paparazzi swarming upon her as she arrived home in London at 1AM.

The 21-year-old can be heard yelping amid the flashing cameras, almost taking a fall. Watch above.

"1AM and 15 hours at work and this is what I have waiting for me. At least I am nice, if I was gonna fall over, they would definitely not tell me grrrrrrrrr," Cara captioned the Instagram video.

The press pack were hungry to get the first snap of the Victoria's Secret model since pictures emerged of her ex Michelle Rodriguez kissing Zac Efron.

However, Cara omitted any mention of Michelle in her latest Twitter spray against the press.

"I got home last night after a 14-hour day at work to see around 12 paps waiting for me. I just wanted to see my bunny and go to bed," Cara wrote. "Still more press poop spilling out their a---s/mouths! Must be a case of journalist diarrhoea at the moment.

"Dear journalists, there is so many more important things going on in the world. You effect what people read. Have some respect for your jobs."

Cara was last seen with 35-year-old Fast and Furious actress Michelle partying in London in May after months of public PDAs (see video below).

While the pair never officially confirmed their romance, they had been inseparable for the past few months, including a romantic holiday in Mexico.

Now, Michelle's reported to be dating 26-year-old Zac after the unlikely couple were photographed kissing on a yacht in Sardinia.
