Pop super star Rihanna received a gift from a shoe designer and then decided to give her fans a gift of their own - the Diamonds singer posted a racy picture of herself on Instagram Tuesday.

She posed topless while wearing a pair of custom Prada thigh-high boots, a white thong and suspenders. Rihanna thanked Prada's head designer Miuccia Prada for the gift in the photo's caption, saying, "Gotcha b*tch tip toeing on my marble flo'!!!Sick a** custom Prada boots! Miuccia you RULE!!! Thank you."

Rihanna received over 250,000 "likes" for showing off her bottom to her 5 million-plus followers.

The singer appears on two separate covers of ELLE UK's recently released April 2013 issue. In her interview, she told the magazine why she chooses to document the most intimate aspects of her life on the social media site.

"I Instagram everything about my life, whether it's smoking pot, in a strip club, reading a Bible verse - how crazy, I know! - or hanging out with my best friend, who happens to be Chris," Rihanna admitted. "Everybody wanted to know what was happening in my life. 'Is she a drug addict?' No. 'Is she an alcoholic?' No. 'Is she a victim?' No. That's when I got the gun [tattoo]. It was a symbol of strength. I'll never be a victim."

Rihanna said she simply wants to be honest with her fans.

"That's why I'm posting pictures of myself smoking pot, to tell the truth about myself. I've got so much to think about, why bring all this extra s*** by being dishonest?"

Rihanna made a brief appearance in London on Monday to promote the release of her Rihanna for River Iskand fashion line. She wore one of her own designs: a black maxi-dress with a thigh-high slit with a cutout back.
