The 26-year-old star is famed for her wacky dress sense and larger-than-life personality.

Ke$ha takes style inspiration from Rolling Stones guitarist Richards.

Speaking to British magazine Look: ''I like taking a masculine style and making it sexy. I love suits and I always look to Keith Richards.

''If I could look like Keith Richards with t**s that'd be great.''

Ke$ha also revealed the reasoning behind her eclectic dress sense.

The star - who admits she once dyed her hair a drastic shade of blonde to look like an animal - says she takes inspiration from a range of people, places and things.

She added: ''I go from one extreme to the other. I've been influenced by everything, 80s wrestlers, at one point I wanted to look like a white lion, which is why I dyed my hair white.''

The star already has 4 of his own clothing lines, namely Billionaire Boys Club, Billionaire Girls Club, Bee Line, ICECREAM, and will now join as a mentor on the show, which features 12 contestants who will take on challenges over 10 weeks for the chance to win the opportunity to design outfits for celebrities.

Salaam Coleman Smith, president of Style Media, spoke about the addition to the panel in an official statement: "We are delighted to have Pharrell, who is a driving force in both the music industry and fashion world, serve as a mentor on Styled To Rock."

"Pharrell's unique aesthetic and commitment to individuality combined with Rihanna's vision for this series will enable our aspiring designers to hone their craft and learn from the very people who set the trends."

Meanwhile, Rihanna's summer collection for River Island will hit stores next week (May 15) and she explained that it was inspired by the style of her own team: "I made a piece for everybody in my crew, we all have different body types and different tastes - some are braver than others. I think like that because that's how women in the world are. We're all different, we like different things, we have different occasions and different moods."

Now at age 58 Kenni is back with his new single ‘One of These Sundays’. Having already entered the prestigious Music Week club charts, Wenna is expected to continue this rise with the infectious new single. Moving in a different direction from Real Lite, the track is an upbeat dance work suited to the club setting. Combining thumping four on the floor beats and melodic synthesisers, Kenni’s distinctive voice and acoustic guitar emerge out of this. Competing with club tracks from some major names, ‘One of These Sundays’ is certainly prepared for the test.

Updates on Kenni Wenna’s club chart position will be coming in the next few weeks.

During a behind-the-scenes clip from her InStyle photoshoot, the 'Come & Get It' beauty confessed that she can't stick to a budget when it comes to treating herself to accessories:

"It's really funny, somebody asked me about how much I spend on clothes. I actually really like being a bit more cheap when it comes to my clothes, but when it comes to shoes or bags, that's where I splurge."

"I love buying a really pretty bag or a nice pair of shoes and the rest of my outfit will cost like, $20. I'm that girl, for sure. I'm a sucker for shoes and handbags."

She also opened up about her style inspirations and admitted that she loves Kate Winslet: "From the red carpet it's Charlize Theron and I love Kate Winslet - I just think they're so classic and it really looks like they have the most perfect skin in the world. I would definitely say those are my two."

The global star announced earlier this year that she would be teaming up with the fashion retailer for her first ever clothing line.

She said it would be released in spring 2013 - and it seems the 'Diamonds' singer has now helped shoot the collection's advertising campaign.

Posting a picture of herself and models on Instagram and Twitter, Rihanna said that she had teamed up with Mario Sorrenti on a two-day shoot. She revealed:

"My bitches so Bvalgari... Just directed my first ad campaign for my new collection with River Island, Spring/Summer 2013!! And that's a wrap at the end of a 2 day shoot w/ MARIO SORRENTI."

As previously reported, Rihanna has been hinting at a reconciliation recently with former boyfriend Chris Brown after posting images of the pair together online.

Brown, who assaulted the singer in 2009, also featured on her new album track 'Nobody's Business'.

In a post released today (July 16) on her official website, Rihanna confirmed that the range will launch in spring 2013 and said that she has been wanting to design clothes for a long time.

She added that she values River Island's British heritage, taking time to praise London in the process. Rihanna said:

"I've been wanting to design my own collection for some time. River Island is the perfect partner for me to collaborate with and working with a British, family run business also really appealed to me. I find London really inspiring and River Island loves to have fun with clothes. I'm looking forward to working with them and creating something really special."

Rihanna meanwhile later posted a photo of herself on Twitter with two other ladies in bikinis.

The singer and TV personality has collaborated with a "top shirt designer" on the collection, which will be available to buy on his official website from tomorrow (July 6).

His website says that he will be releasing ranges for men and also for children, with the men's collection revolving around shirts and t-shirts.

Speaking about the launch of his clothing empire, Andre said:

"I am thrilled to be launching my new clothing collection. The modern man likes to look after themselves and I am no different. I am proud to be offering a new range for them to choose from."

He continued: "The children's collection is just the beginning, with another collection coming out in late September 2012 which will be much bigger and I am very excited about."
