Jennifer Lopez Leg Pictures at 2013 Grammy Awards

Jennifer Lopez made a grand entrance at the Grammys in LA today wearing a sexy slitted gown by Anthony Vaccarello. She told Ryan Seacrest that she read CBS' guidelines for dressing but wanted to show "a little shoulder, a little leg." She arrived on the arm of boyfriend Casper Smart and the duo posed for photos on their way down the carpet. J Lo isn't nominated at this year's show, but she will be taking the stage to present an award. Other presenters include Beyoncé Knowles, Faith Hill and Keith Urban. They won't be the only famous faces in the spotlight, since Taylor Swift and Carrie Underwood are expected to perform and many other big musical names are up for honours.
