Career
She starred in the NBC series Friday Night Lights as Lyla Garrity, the 2011 film The Roommate, and a reboot of the 1970s television series Charlie's Angels. She made several appearances in the first two seasons of Parenthood.
When Kelly was 19, after graduating from Valley High School in Albuquerque, Kelly returned to Los Angeles. While on a test shoot for a modeling agency, she was approached by a former Playboy Playmate interested in managing her, and who placed Kelly as a receptionist at a surgeon's office who would provide Kelly breast augmentation in exchange for hours worked. She ultimately decided against the procedure, leading to her being fired. However, the exposure to the medical field prompted her to attend school for a year to become a surgeon's assistant; afterward, she worked as a scrub tech. She spent four years in that vocation while also auditioning as an actress before landing the new NBC television drama Friday Night Lights, based on the high school football movie of that name. In the interim, she had small roles in movies and shows, including the film State's Evidence, and a recurring guest role on the TV sitcom What I Like About You.
In 2010, Kelly was named "Sexiest Woman Alive" in the annual Esquire magazine feature. She accepted a role in the Off Broadway play Love, Loss, and What I Wore for an April 27 through May 29, 2011 run with Conchata Ferrell, AnnaLynne McCord, Anne Meara, and B. Smith.
She played a lead role in the remake of the television series Charlie's Angels during the 2011-12 United States network television season.
She joined an eight-day, four-country United Service Organizations tour in December 2011 with Chairman of the Joint Chiefs of Staff General Martin Dempsey, Robert Horry, Jordin Sparks, Thomas Miles and Sergeant Major Bryan Battaglia.
