When it comes to the red carpet circuit, Rihanna is never one to disappoint. In fact, the star, who rings in her 27th birthday today, keeps us on our toes throughout awards season. Case in point: the flawless Giambattista Valli cupcake gown she wore at this year's Grammys.

We first caught glimpses of the awe-inspiring dress toward the end of the Grammys red carpet, and later became fully obsessed with the breathtaking hot-off-the-runway creation.

The newly minted creative director of Puma certainly has a gift for switching between sweet and sexy styles, opting to take on a custom, see-through fishnet dress that was hand-embellished with more than 216,000 Swarovski crystals at last June's CFDA Awards, where she won the Fashion Icon Award. In honor of Rihanna's risk-taking sense of style and her birthday, we rounded up her most memorable looks on the red carpet, from a lace Stella McCartney number in 2011 to present-day showstoppers.
