There's No Doubt About It: Demi Lovato Had the Best Grammys Weekend

Demi Lovato's first appearance at the Grammys was one to remember. The singer and songwriter started her busy weekend three days ahead of her performance to honor MusiCares Person of the Year Lionel Richie at the ceremony held at the Staples Center in Los Angeles on Feb. 13. From the sweet Valentine's Day break she took to celebrate with boyfriend Wilmer Valderrama (and the sparkly diamond ring she got from him) to her red carpet appearance in a sexy black look, and all the way to her killer performance of "Hello," these were the best moments of her weekend.
