"Hey Baby" was chosen as the lead single from "Rock Steady" to represent the band's more "upbeat and confident" attitude for the album. It was commercially successful in the United States and enticed a younger audience to No Doubt. The song debuted at number 36 on the "Billboard" Hot 100, remaining on the chart for half a year. In its third week, the song became the band's highest charting single, eventually peaking at number five for two consecutive weeks, later broken when "Underneath It All" reached number three. It was successful in the mainstream music market, topping the Top 40 Mainstream and reaching the top ten on the Top 40 Tracks and Adult Top 40. The song had significant crossover success and reached number five on the Rhythmic Top 40 chart. At the 2003 Grammy Awards, the song won the award for Best Pop Performance by a Duo or Group with Vocal, and No Doubt performed a medley of "Underneath It All" and "Hella Good" at the show.
