Mandy Moore came into our lives dancing and singing about "Candy" in 1999, and she's stayed in the spotlight since. She turns 29 today, April 10th, and she's taking her twenties by storm.
While some of her outfits in the early 2000's might not be "sugar to [our] heart," the singer and actress has definitely evolved over the years, and we've come to love her style! She's big on attending events during fashion week, the Costume Institute Gala at the Met and the CFDA Fashion Awards.
Moore wasn't satisfied with just a singing career, and has graced both the silver screen and the big screen, with roles in The Princess Diaries in 2001, A Walk to Remember in 2002, Saved! in 2004 and Entourage in 2005.
She stepped into the fashion world in 2005 by releasing her own line, named Mblem., contemporary knits and cashmere sweaters geared towards tall women like herself. She unfortunately had to shut down this line in 2009, but also had happy news that year when she married musician Ryan Adams. She has continued performing on the stage and screen, recently voicing Repunzel in Tangled in 2010.
At the moment, Moore is at work on a new series for CBS, and we can't wait to see her on our TV screen again!
