That's the question since "badgalriri" mysteriously vanished from the social media site a little over a fortnight since.
She'd been on thin ice. After posting a topless magazine cover, Rihanna had been slapped with a temporary ban from the site for her skin-baring habits.
But when it lifted, RiRi went one better and deleted her account altogether.
With it went a carefully crafted suite of swimsuit selfies, Barbadian street festivals and dope cakes.
Unlike her contemporary Beyonce - whose posts seem as tightly managed as North Korea's nightly news - Rihanna seemed hellbent on cataloguing the truth of her celebrity lifestyle.
Bar Kim Kardashian, she was the Celebrity Queen of Social Media.
But it looks like her reign is over.
Along with her lost Instagram, RiRi's been suffering attacks on her remaining social media front: Twitter.
The Umbrella singer copped an online spray from Charlie Sheen today after declining to meet his fiancee while both were dining at the same Californian restaurant.
"Sorry we're not KOOL (sic) enough to warrant a blessing from the Princess. (or in this case the Village idiot)," he tweeted.
"It was a pleasure NOT meeting you."
He even took a shot at the pixie-crop pink wig she's been sporting lately: "I'm guessing you needed those precious 84 seconds to situate that bad wig before you left the restaurant."
But some would argue Sheen's tiger blood-fuelled rant was just desserts for Rihanna.
Last week, she came under fire for mocking a diehard fan who tried to recreate a Alexandre Vauthier jumpsuit she wore in 2010 for her prom outfit.
With its inbuilt cape and plunging neckline, Alexis Carter's outfit was soon christened "Prom Bat" by some social media users who poked fun at it online.
Among them was the Bad Gal herself, who tweeted a picture of the fan alongside the Wu-Tang Clan's bat emblem.
"Alexis Carter u rocked that outfit, u looked fierce girl. Rihanna doesn't deserve you as a fan," one supporter tweeted.
Another said the young girl should never have had to endure being "torn down by your idol".
Despite the backlash, the controversial singer's appetite for selfies hasn't abated - at the time of writing, she'd managed to post three within a half hour.
But like a viral Marie Antoinette, it seems RiRi is increasingly isolated from her once-loyal subjects.
Let her eat dope cake, perhaps?
