Chopra's main vocal influence was her father, who helped develop her interest in singing. She used her vocal talent early in her pageantry career. Her first recording, the song "Ullathai Killathe" in the Tamil film Thamizhan (2002), was made at the urging of her director and co-star, Vijay (who had noticed her singing on the set). She declined to sing playback for "Tinka Tinka" in her film Karam (2005), preferring to concentrate on her acting career, but later sang the song live on the television programme Sa Re Ga Ma Pa. Chopra recorded an unreleased song for Bluffmaster! (2005). In August 2011, Universal Music Group signed Chopra to a worldwide recording agreement with DesiHits. The deal indicated that her first studio album would be released by Interscope Records in North America and by Island Records elsewhere.
Chopra is a supporter of environmental charities and is brand ambassador for NDTV Greenathon, an initiative to support eco-friendliness and provide solar power to rural villages without electricity supplies. She appeared with children in an animated video to support the cause, and removed rubbish from the banks of the Yamuna river in Agra to increase awareness of environmental issues. During the third and fourth editions of Greenathon, She adopted up to seven villages to provide with a regular supply of electricity. She adopted a tigress in 2011 and a lioness in 2012 at the Birsa biological park, paying for both animals upkeep for a year. To promote organ donation, Chopra pledged to donate her own organs after death and was co-keynote speaker at the University of Pittsburgh Medical Center's Bollywood-themed 20th-anniversary celebration of its liver-transplant programme in 2012.
