Hailee Steinfeld began acting at the age of eight by taking on roles in short films before simultaneously appearing on several television commercials and guest starring on television programs. Her hard work and determination were paid off after she was chosen out of 15,000 girls for the role of Mattie Ross in the 2010 film "True Grit". She was nominated for an Academy Award for Best Supporting Actress, a Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Supporting Role, and a BAFTA Award for Best Actress in a Leading Role. It was the role that catapulted her to prominence and granted her notable roles in future projects, including as Juliet Capulet in "Romeo and Juliet", as Zoey Renner in "3 Days to Kill", and as Violet Mulligan in "Begin Again". She, moreover, could also be seen starring as Emily in "Pitch Perfect 2" released in 2015.

Steinfeld was born December 11, 1996 in Tarzana, Los Angeles, California. Her older brother Griffin Steinfeld is a NASCAR driver. In 2011, she was announced as the face of famous brand Miu Miu. In the same year, she was one of the presenters at the prestigious Golden Globes.

Steinfeld began her career as a pop star after landing a record deal with Republic Records in 2015. Her debut single, "Love Myself", came out in summer that year and became a radio hit. It peaked at No. 30 on Billboard Hot 100 and has been certified platinum in several countries. The song was lifted off the star's debut EP "Haiz" which was released on November 13 that year.

Steinfeld scored her biggest hit yet in 2016 with dreamy and catchy EDM-pop tune "Starving". She teamed up with duo Grey and DJ Zedd for the track, which was released in July and has so far reached No. 12 on Billboard Hot 100.
