Rita Ora marks Kate Moss' 45th birthday with saucy bed snap on Instagram

Rita Ora posted a saucy birthday tribute to Kate Moss as she shared a snap of the pair cosied up in bed.

Ora, who signed to Moss’ modelling agency last year, paid homage to her pal on her 45th birthday with the ultimate throwback snap of Moss fast asleep.

Alongside the posts, Ora wrote: “There’s only one KM. Happy birthday!! You do so much for so many here’s to your day! you deserve the world!

“I love you always and forever and I’m so happy to call you my friend. Here’s to many more memories and laughs! #major @katemossagency.”

Moss marked her landmark birthday on Wednesday, having enjoyed a night out at China Tang at The Dorchester on Tuesday night.

Moss was joined by her boyfriend Count Nikolai Von Bismarck and pal Stella McCartney at the lavish venue.

McCartney celebrated in style with her supermodel friend, uploading a video of the two at midnight wishing her “shlag wag” a happy birthday before giving her a kiss.

She later posted a photo of the pair, writing: “To one of my oldest finest funniest friends... happy happy birthday. I love you xxx Shlag!!”

Ora announced that she was officially making her first foray into modelling last summer when she signed to Moss’ star-studded agency.

At the time, the Anywhere singer told The Sun: “Kate has always been a mentor and life-long friend. It's a real honour to be working with her.

“I have watched her career and business grow, and establish itself as one of the most important and recognisable brands. She is a real inspiration, and when we discussed going in to business together, it seemed natural.”
