Rihanna Resorting to Cheap Publicity? 'Diamonds' Singer Poses Topless [PHOTOS]

It looks like R&B singer Rihanna is resorting to cheap publicity for her new album "Unapologetic" as she has posted her private photos including her posing topless and another photograph of her ex boyfriend Chris Brown.

The 24-year-old singer released her seventh studio album, "Unapologetic" on November 19, 2012, and its lead single "Diamonds" has reached number one on the US Billboard Hot 100.

The "We found Love" singer posted her topless photo on her twitter page after her wonderful performance on X Factor on Sunday night.

She was drenched to the the skin while singing the song "Diamonds" on the quarter finals of the reality show, revealing her curves. She later uploaded a photo in which she is seen in black underwear and without a top.

She had earlier posted a photo of her ex boyfriend Chris Brown lying face down on a bed after tweeting that she would meet her lover.

"All alone in my big ole jet!!! See u soon lover," she tweeted. "#777Tour is a wrap! Thanks to everyone who was a part of this. It was an incredible experience for my fans and I! #UNAPOLOGETIC is OWT."

Reports were doing the rounds that the ex-couple were in love again but Rihanna had earlier denied it.

They sparked off reunion rumours after they were caught kissing at Chris' website launch party last month, and then Chris Brown attended Rihanna's Halloween party dressed like an Arab terrorist.

It may be recalled that Chris Brown was arrested in 2009 for assaulting his then girlfriend Rihanna at a pre-Grammy Awards party. He will remain on probation until early next year for the assault.
