Aastha Gill was born on 24 June 1991 in Delhi, India. She studied journalism at the Vivekananda School of Journalism and Mass Communication in New Delhi and initially worked in advertising and at a news channel.

She made her playback singing debut with “Dhup Chik” from the film Fugly (2014), alongside Raftaar and Badshah. She gained major popularity with “DJ Waley Babu” (2015), which became a major hit and established her as a prominent voice in India's contemporary pop and Bollywood music scene.
Aastha later released independent songs such as “Buzz” and “Naagin” and collaborated on popular tracks including “Proper Patola” and “Paani Paani.” She has also appeared on television, including as a contestant on Fear Factor: Khatron Ke Khiladi 11 and as a judge on music-related programs.
