The 25-year-old singer, who was performing on her Diamonds World Tour in Florida on Saturday, posted an Instagram photo of herself, smoking what appeared to be a joint backstage.
Rihanna kicked of her weekend antics by celebrating 420, known in the US as ‘Weed Day’.
The candid snap was accompanied with the message: ‘#420 it's a celebration b**s!! Thank you to all my ft. Lauderdale and Miami fam that came through #DWT #backstageLife.’
Rihanna voiced her appreciation of her fans as she tweeted a photo of a marijuana leaf cake she had received from one of them, along with the phrase: ‘What did I do to deserve the epicness that is my fans??!!!’

The Bajan beauty also posed with Victoria's Secret Angel, Adrianna Lima, who dropped by for a surprise visit to congratulate the singer on her show.
She playfully wrote: ‘Only bad b**s get backstage on the #DIAMONDSWorldTour #nobasiczone @adrianalima.’
No stranger to strip clubs, Rihanna quickly moved the party on to the King Of Diamonds Gentlemen's Club in Miami, where she posted a series of eyebrow-raising snaps.

In one of the photos captioned ‘I still got my money #420’, she appeared to be receiving a lap dance from a stripper.
The Pour It Up singer's final photo of the night showed her counting money with the caption: ‘Wild for the night, phuck being polite!’.
On Sunday morning, following her wild night of partying with strippers, the songstress tweeted to her 29.3 million followers:

‘Lastnight one of my fantasies came to life! I got to see K.O.D strippers dance for me to the stripper song I made! #PoItThePhuckUp’.
Rihanna ended her weekend by having a chilled day of sipping coconuts by the pool as she posed in a Matthew Zink string bikini and Miu Miu sandals for an Instagram photo.
