She threw a Halloween party to remember on Wednesday night and made sure she was the belle of the ball in her all-green ensemble.

And the following morning, Rihanna decided to show off the signs of her eventful evening by uploading a topless picture of herself to her Instagram account.

Sitting up in bed with her green veil and tiara still on her head, the 24-year-old holds her hand to her face a she cuts a seductive figure in the racy snap.

The caption which accompanied the picture read: 'The morning after! Hello November'.

In the image, the Where Have You Been singer's latest inked design can be seen as she tries to cover her modesty with her arm.

On Wednesday evening Rihanna made sure she went all out for her fancy dress party.

The popstar looked like a carnival queen, wearing a green veil and sparkling green dress as she hosted the bash at Greystones Manor in West Hollywood.

Arriving fashionably late with friends Evelyn Lozada and Shaniece Hairston, the star looked like she'd put a lot of effort into the outfit in a complete transformation from her demure look earlier in the day for the Halloween parade.
