As audiences gear up for the romantic musical drama A Star Is Born, due in theaters Friday (Oct. 5), Bradley Cooper makes his Billboard chart debut thanks to the duet "Shallow" with co-star Lady Gaga. The ballad debuts at No. 14 on the all-genre Digital Song Sales chart (dated Oct. 6) and No. 4 on the Pop Digital Song Sales survey with 12,000 downloads sold in the tracking week ending Sept. 27, according to Nielsen Music.

Notably, the track debuts with just a half-day of tracking, as it was released on the final day of the Sept. 21-27 tracking week. As such, the song will likely make a sizable jump on next week's charts (dated Oct. 13) and could debut on the streaming, airplay and sales-based Billboard Hot 100 next week. According to building Nielsen Music data, "Shallow" is the top-selling song of the current tracking week (ending Oct. 4), with over 35,000 sold so far. The song, the lead single from the A Star Is Born soundtrack (also due Oct. 5), was co-written by Gaga, Mark Ronson, former Dirty Pretty Things vocalist Anthony Rossomando and Miike Snow vocalist Andrew Wyatt.
