The country singer was just 15 when she won her first (and only, so far) Grammy Awards -- nabbing Best New Artist and Best Female Country Performance after her breakthrough hit "Blue."
And 15 years later, she's still making headlines!
Of course, now Rimes is known more for her personal life than her music -- thanks to controversial relationship with now-husband Eddie Cibrian (whom she met when they were both married to other people), scrutiny on her weight and her endless parade of risque bikini pictures.
To celebrate the singer's 30th birthday, we've pulled together 20 of her best bikini shots. Some she posted herself on Twitter, others taken by the paparazzi she's become very comfortable with through the years.
