Rihanna's Birthday: Singer Turns 24, Style Evolution (PHOTOS)

Since hitting the scene in 2005 with her first single "Pon de Replay," Rihanna has consistently wowed us with her unique voice and killer style.

From the sexy peek-a-boo Jean Paul Gaultier gown she wore at the 2011 Grammys to her super edgy street style, RiRi's fearless fashion sense definitely keeps us on our toes. And let's not forget the Barbadian beauty's ever-changing hairstyles and color (red is our favorite).

Already the face of Armani Jeans and Emporio Armani Underwear, Rihanna recently announced she'll be launching a fashion reality show in the UK this summer--yet another reason she's one of our favorite fashionistas.

So in celebration of her 24th birthday this Monday, here's a look at Rihanna's meteoric rise to style star.

What's goin on with that girls brain? Why she hanging round that nasty Chris Brown? Does she want more bruises and busted up noses?

Great 24! Perhaps soon she will become comfortable with her body and sexuality and realize that everyone has both as well, then she can start to cover it up and stop hanging out the "LOOK AT ME" sign.

Rihanna is by far one of the most beautiful women in the world. She has it all; looks, body, talent and the whole package. What a lucky girl!!! In spite of the negative comments about her clothes, I think she looks amazing in everything she wears. These people are just jealous losers.

Is it just me or has her skin tone gotten much lighter in many photos over the years? She's a beautiful girl for sure!
