Guess Who This Birthday Cutie Turned Into!

Before this adorable gal launched her music career on Myspace back in 2005, she was just your average 1-year-old blowing out her birthday candles in London, England.

This cute kid has been 'mean muggin' since 1985 ... and according to her Instagram page, she loves a candid mirror selfie! Growing up with two parents already in the entertainment industry, it comes as no surprise that she rose to stardom after the release of her first song "Smile" back in 2006.

You probably heard her on singer Pink's "True Love" track and on rapper T-Pain's "5 O'Clock" song.
