Kajal Aggarwal is an Indian actress, who has appeared in Telugu and Tamil films. She made her acting debut in the 2004 Hindi film Kyun...! Ho Gaya Na, playing a minor supporting role, before becoming a leading actress in the major South Indian film industries. She rose to fame after her performance as Yuvarani Mitravinda and Indu in the 2009 Telugu blockbuster film Magadheera.

She began her acting career in the 2004 Hindi film Kyun...! Ho Gaya Na, in which she enacted a minor supporting role as the friend of Diya, the film's lead female, played by Aishwarya Rai. Only 3 years later, she got her next acting offer, which was veteran Tamil director Bhrathiraja's Bommalattam. The film, however, got delayed and released only in late 2008.

In the meantime, she made her debut in the Telugu film industry and played her first leading role in Teja's Lakshmi Kalyanam alongside Kalyan Ram, which did not do well at the box office. Later that year, she appeared in the Krishna Vamsi-directed film Chandamama, which became her first major successul film.

In 2008, she had her first Tamil-language film release, which was Perarasu's action entertainer Pazhani. The film, in which she shared screen space with Bharath was a commercial success. Following this film, she had two more Tamil releases that year with Venkat Prabhu's comedy-thriller Saroja, in which she did a guest appearance, and finally Bharathiraja's investigative thriller Bommalattam.

Especially the former film went on to become a commercial as well as a critical success, but both films failed to boost her career as her roles were too insignificant. Both her Telugu releases that year, Pourudu and Aatadista opposite Sumanth and Nitin, respectively, neither received positive reviews nor were successul at the box office.

2009 she had four releases, three of which in Telugu. Her only Tamil film that year, which was Saran's Modhi Vilayadu, released first; it garnered mixed reviews and poor box office returns. Next she starred in the Magadheera, in which she essayed double roles for the first time. The film recevied universal critical acclaim as did the lead actors, including Kajal Agarwal, for their performances.

Agarwal, particularly, was praised for her portrayal of a princess, Yuvarani Mithravindha, in the film. The film was also commercially highly successful and broke several records, emerging as the highest-grossing Telugu film and as one of the biggest box office hits in India. Following Magadheera's phenomenal success, Agarwal became one of the most sought-after actresses in the Telugu film industry, catapulting her into the main foray of lead Telugu actresses.
