Rihanna will have to say "ta ta" to Instagram if she can't keep her clothes on.

The social networking site threatened to shut down the sexy songstress' account after she posted topless photos of herself on Tuesday, TMZ.com reported on Wednesday. According to TMZ, Rihanna received an email from Instagram, which bans nude photos, threatening to remove her account if she posts any more naked pics.

Instagram also took down the revealing photos, which came from the 26-year-old's cover shoot with the French magazine Lui, from RiRi's account.

But that didn't stop her from sharing the snaps with the world, posting them on Twitter instead.
