Rihanna will team up with Chris Brown, Adele, Katy Perry, Taylor Swift, Paul McCartney, Foo Fighters, Bruno Mars, Kelly Clarkson, Jason Aldean and Nicki Minaj are also confirmed to perform live at the 54th annual awards show, which will be hosted by LL Cool J and take place in Los Angeles.

Rihanna was spotted in a transparent top sans bra for a night out in Los Angeles.

The Umbrella hitmaker had teamed her peek-a-boo top with gold accessories and Simon Cowell’s trousers, the Sun reported.

“All these bitches screaming that 2pac back ? #THUGLIFE,” tweeted the pop star, who already has around 14 tattoos including one with her best friend’s birthdate on her shoulder and another on her chest that reads “Never a failure, always a lesson.”

Rihanna enjoyed her free time before she duets with Coldplay at Grammy’s Awards show in Hawaii in bikini.

For Armani’s upcoming season, however, Rihanna went with a different look, sporting longer dark hair instead. And although her hair changes, the idea remains the same, as the 23-year-old star strips down to the bare essentials once again.

The latest ads, snapped by Mert Alas and Marcus Piggott in Dublin, tap into her sultry, more romantic side as she takes us to her “California King Bed,” posing in a lacy bra and panties set and a silk-printed cami with darker, flowing locks.

Rihanna hasn’t let clothes get in the way of her vacation. She wore only a tiny white bikini in all but one of the photos she tweeted. She even worked out in her swimsuit.

“Haha, come tap this @Khloekardashian!!!” the 23-year-old singer tweeted along with the workout photo.

The 23-year-old sizzled in a series of sultry photos taken from her latest underwear campaign for Armani, and now she’s posted a few sexy photos of her own on Twitter.

The Talk That Talk singer posted the words ‘just for u’ alongside a frontal view of the herself to an unsuspecting follower after they complimented her on an earlier shot.

The We Found Love singer obviously realised how good she looked as she shared her pictures with fans on her Twitter account, which has an approx. 12 million-strong following, reported the Daily Mail.

She posted a rear shot, showing off her taut derriere with the caption “Wake…Bake…#CAKE.” She later tweeted: “I love u so much! Can’t believe we’re here already… #12Milli thank u.”

The singer has been holidaying with friends in Hawaii for the past few days and has even been spotted smoking a suspicious looking cigar.

It’s been a relaxing few weeks for the singer from Barbados.

She jetted into Hawaii at the weekend after spending a few days in Los Angeles, where she was seen sitting court side at a couple of basketball games.

Rihanna is taking her second stab at being the brand’s face and body and is looking as seductive as ever.

The singer showed off a cropped blonde look in her first campaign but she has gone dark for the new adverts.

Rihanna lingerie advertising campaign for Armani was voted the sexiest set of 2011 so it’s no surprise to see her back showing off the latest line.

The 23-year-old “S & M” singer was seen taking a leisurely stroll on the beach in Hawaii on Monday, and showed plenty of skin in a pink cover-up.

Rihanna appeared to clear up exactly what she has been smoking by quoting some lyrics from rapper Drake’s song Up All Night on her Twitter page.

She wrote: ‘Kush rolled, glass full… I prefer the better things!’ Kush refers to a type of cannabis found mainly in Afghanistan, Pakistan and India.

Rihanna’s courtside leg show was enough to rival the Lakers girls dance routines, and enough to distract even the most focused NBA star.

Dressed in a blonde bob wig and a multicolor outfit, Rihanna performed all her hits!

Rihanna tweeted: “I sell out ARENAS….I call that gettin’ DOME.” Among her hits performed included “Only Girl”, “What’s My Name”, “S&M”, and of course her new track “We Found Love”.

“LONDON TOWN so #illy,” Rihanna tweeted before the show!

As we can see in this pics, Rihanna broke out some vintage ripped daisy dukes, suspenders, nipple rings, and a blonde wig on the set of her latest video for her new single “You Da One.”

Sporting a red tartan dress, surrounded by giant cardboard furniture, the red lipstick-loving, 23 year old Rhi Rhi shocked the studio audience with her outrageous footwear as we all spotted what was written on the trendy runners.

Apparently Rihanna was asked by X Factor bosses to tone down from her raunchy act in last year’s final

A source said that this film is a sexy movie with big budget.
For this film, Rihanna reportedly has several times acting exercise.
