The TOWIE star, 23, decided to channel "old school Beyoncé" when she got ready to see the singer perform at London's O2 Arena last night (28 February).
In a series of tweets, Sam shared her feelings of excitement with her followers and posted a picture of her cute crimped hair.
She wrote: "Yes @Beyonce tonight and yes I'm crimping my hair old school Beyoncé ahh so excited."
She also said: "@Beyonce I'm coming for u."
In the picture, she can be seen wearing a black crop top with white slogan, which showed off her super-slim waist - although the reality TV star has always been slim, Sam's admitted to losing weight after her recent diagnosis of Crohn's Disease.
Sam struck a pose with best friend Ferne McCann, too, who was all smiles despite her recent relationship woes.
Fellow TOWIE star Ferne is currently torn between ex-boyfriend Charlie Sims and new love interest Frank Major. Although she did seem to post a message to both of them when she tweeted: "I wish I was drunk in love."
Pregnant Billie Faiers also looked her best for the gig in a stylish monochrome outfit, which concealed any sign of her blossoming baby bump.
Beyoncé continued her Mrs Carter Show tour in the UK, this time in the famous London venue.
She performed hits including 'Crazy In Love', 'Single Ladies', 'Halo' and 'Drunk In Love'.
Husband Jay-Z joined her onstage to the delight of fans - including Sam, Billie and Ferne! - while X Factor winner Sam Bailey had the honour of being the support act.
Sounds like an amazing night...
