Rihanna has posted a topless picture of herself on her Instagram account.
The pop star posted the snap of herself sitting up in bed, wearing just a green, bridal-style veil and preserving her modesty with her arm.
It appears to have been taken on Thursday morning, following her Halloween party on Wednesday evening - because she wrote: "The morning after! Hello November."
Ri-Ri had worn the green veil at her party the evening before, which also saw Chris Brown dressed as a terrorist and Paris Hilton dressed as comic book hero Robin.
Rihanna was crowned West Hollywood's Queen Of The Carnival on Halloween.
