62 photos that chart Rihanna's style journey: 'SOS' singer to billionaire mum-to-be

Rihanna may only be 33, but she's been a red-carpet regular for nearly half her life.

The singer, whose first single Pon de Replay was released in 2005, has seen her empire grow in those 17 years.

And now, her family is growing. The Barbadian star has announced she is expecting a baby with her rapper partner, A$AP Rocky.

To reveal her pregnancy, the couple took a stroll around a snowy New York. Despite the frigid temperatures, the Diamonds singer and beauty mogul showed off her bump in a long open pink vintage Chanel coat with body jewellery and ripped jeans. The images were taken by photographer Miles Diggs, known as Diggzy.

The star, born Robyn Rihanna Fenty, has transformed from chart-topping singer into a savvy businesswoman, launching a make-up line and fashion label in recent years. She's also added actress to her list of talents, with roles in films including Ocean's 8 and Guava Island.

Her chameleonic talent also extends to Rihanna's style journey, with the star morphing from mid-noughties pop singer, wearing embellished tees and distressed jeans, to one of the most exciting A-listers to walk the red carpet.

Indeed, if Rihanna is attending the Met Gala, you know it'll be a moment in fashion history.

While the multi-hyphenate tends to favour some of the world's most illustrious maisons, from Dior to Givenchy, she's not afraid to switch things up, embracing emerging labels and more avant-garde brands.

Here, we take a look back through her red carpet retrospective to see how Rihanna's style has evolved in the past 17 years.
