We all have those days when we're feeling a little groggy but while ordinary folk head to the nearest Starbucks for a pick-me-up, celebs like Rita Ora go for something a little more drastic - by having vitamins injected into their bums.
Rita is the latest celeb to join the craze for having B12 vitamin supplement shots in a bid to keep her energy levels up.
The 'RIP' singer and her friend Emily Rose can be seen preparing to have the injections in a new snap that Emily uploaded to Instagram.
"B12 time!" she wrote. "I'm so ready for mine as you can see!!! @candicebirnshairstylist is not just an amazing but she gives B12 shots too! #healthiswealth."
Other busy stars who are fans of the vitamin shots include Madonna, Justin Bieber, Katy Perry, Justin Timberlake as well Victoria Beckham, who is said to have used them during each of her pregnancies.
