Who shot ya? Rita Ora gets a hair stylist to inject vitamin B12 supplement... into her derriere!

She lives the jet set lifestyle of an international popstar, so it's not surprise that Rita Ora has looked to the new fad to keep her energy levels up.
And the singer had everyone knowing about it when her friend Emily Rose tweeted a picture of her hair stylist injecting herself and Rita with a vitamin B12 shot.
With the photo, Emily wrote: '#b12 time! I'm so ready for mine as you can see!!! @candicebirnshairstylist is not just an amazing but she gives B12 shots too! #healthiswealth'.

Health boost: Rita Ora and her friend Emily Rose get B12 injections from a hair stylist

The shots are recommended for those who suffer from tiredness, lethargy, feeling faint and becoming breathless as a result of the reduced amount of oxygen in the blood. A lack of vitamin B12 is a common cause for anaemia, but many celebrities have started treating themselves with the injections including Madonna, Justin Timberlake, Katy Perry and Justin Bieber.
Victoria Beckham has also said how much she relied on the supplement during each of her pregnancies..

But Madonna is understably one of the biggest proponents of B12, having recommended it to more than a few celebs, including Justin, and may have been the voice behind Rita's move to the drug.
Ora is the new face of Madge's teen fashion label Material Girl, and no doubt the discussion of health has come up between them, with the American singer's notorious background in keeping fit and healthy.
But Rita seems to be enjoying the perks of being the brand ambassador of a youth label, as she has been tweeting photos of herself wearing items from Material Girl's latest collection.

Clearly the LA lifestyle is rubbing off on the London girl.
