The photo-sharing app and the pop singer have a rocky relationship. Back in September, her Instagram selfie with a slow loris actually prompted a criminal investigation.
She originally posted a few topless photos (NSFW) to her account on Tuesday, but Instagram removed them almost as soon as she posted them. She protested by posting a meme to her more than 12 million Instagram followers.
According to TMZ, Instagram later contacted the singer and told her that if she continued to post nude photos on her Instagram account, she would lose her account.
With that in mind, Rihanna just went and posted all of her Lui photos onto Twitter, which is OK with nudity.
Twitter 1, Instagram 0.
