A day after hosting one of the hottest Halloween parties in California, Rihanna showed that she was still having fun the morning after.

The Barbadian beauty brought in November by posting a new photo of herself on her Instagram account, topless, with her hand barely covering her chest, and two of her tattoos still visible. Rihanna still wore the green veil that was a part of her costume the night before.

Wednesday night Rihanna hosted a party at Greystones Manor in West Hollywood.

Rihanna seemed to be dressed as her favorite plant, as she wore a green gown and carried a bouquet of what looked to be a replica of marijuana leaves. Rihanna has never been one to hide her love of marijuana, often tweeting pictures of herself smoking weed to her followers.

Along with the topless picture Rihanna posted, she wrote the caption, “The morning after! Hello November."

Rihanna often dresses risqué, and going topless lately is nothing new for the pop star. For her upcoming seventh album, titled 'Unapologetic,’ the cover features a nude Rihanna, with plum lipstick, showing off her tattoos, as well as words written on her body, such as “faith,” “fearless,” “victory” and “fun.”
