After a mysterious tweet from the popstar, the rumor mill sprang into action, with fevered speculation that Rihanna might be a new face of Chanel.

She has already teamed up with Italian luxury label Armani for a limited edition line of clothing and lingerie, and now Rihanna is set to conquer the high street by teaming up with UK store River Island.

Rihanna has renewed her Armani contract for another season and the singer’s latest advert for the brand has just been released.

Fans of Rihanna‘s flashy Grammy Awards nails will have the opportunity to get their hands on a limited edition bottle of the 24-karat gold “Amor 24″ polish she sported to the February 12 ceremony.

During the recent awards ceremony the singer’s hands earned as much attention as the plunging Emporio Armani dress she co-designed thanks to the varnish, which retails at $5,000.

Armani has released a video teaser for its underwear campaign starring the singer.

Shortly after launching its men’s campain with tennis player Rafael Nadal, Armani has released long-awaited images for its jeans range starring pop star Rihanna.

The singer is taking over from actress Megan Fox for the campaign, with the second batch of images — for the brand’s underwear line — yet to be brought out.

Rihanna is upping her advertising game at the moment, also having just been named the new face of skincare brand Nivea.

Rihanna let her hair down recently in the French Riviera aboard on Benetti’s stylish 172-ft. superyacht Latitude, which charters out at about $300,000 a week.

The London Daily Mail reports that the 23-year-old star rented the vessel for some R&R following her performances at the UK’s V Festival.

She thrilled paparazzi with glimpses of a toned bikini bod as she paraded around the yacht’s five decks.
