A blockbuster movie and soundtrack, two Grammys, and an Academy Award... just when you thought the A Star Is Born era couldn't get any bigger, Lady Gaga has added another massive achievement to the list. The movie's theme song "Shallow" has skyrocketed to No. 1 on the Billboard Hot 100, becoming Gaga's first number one single in the United States in over eight years. The last time a Lady Gaga song topped the chart was in 2011, when "Born This Way" debuted at No. 1 and stayed atop for six weeks.
