She's known for being something of a style chameleon who likes to switch up her look from one day to the next.

But one look we're not so used to seeing Rihanna rocking is that of demure or girly and on Saturday night the singer shook things up once again by wearing a sophisticated monochrome dress.

The Bajan beauty debuted the look as she stepped out for a spot of dinner at her favourite restaurant, Giorgio Baldi in Santa Monica.

The simple dress featured a v-neck, sleeveless white top half, while the bottom section was a mid-thigh length black skirt.

She completed the feminine looking outfit with a pair of delicate black heels, with two straps.

Keeping her jewellery basic, she wore a pair of gold hoop earrings and a pretty gold bracelet.

She added a splash of colour to the outfit with bold red lipstick.

The sleek look came just a day after she was spotted at JFK outfit dressed in her more common fierce attire.

On Friday the 24-year-old strolled nonchalantly through the airport eating a Hershey chocolate bar, while wearing a black satin varsity jacket, diamante sunglasses, ripped jeans and pair of stiletto shoes.

Despite her tough look, the singer was more than happy to pose for some snaps for some fans, in fact she took it a step further by posing for a 'full on photo shoot' for the plane crew.

After the impromptu photo session, she tweeted: 'Flight attendants just made me do a full on photoshoot in my seat! I better get some free nuts .'

Rihanna was in New York City to attend the opening of her good friend Jay Z's new nightclub 40/40.

It's been a busy week for Rihanna, who as well as having a fleeting visit to the UK, released her latest single Diamonds, which became available on iTunes in the UK on Saturday.

It's been reported that her ex, Chris Brown, has been texting the singer to compliment her on her new tune.

A source told HollywoodLife.com: 'Chris heard the track and fell in love with it and started busting out a few moves of his own when he heard it. He thinks it's a hot song and he's proud of Rihanna and her music.'

'He texted her and was like Love Diamonds. "Am I shining enough?" and she replied back saying "hell yeah.'

Next year, Rihanna will bring her stage show across North America on the Diamonds world tour, which kicks off on March 8, 2013 New York.
