The Diamonds' version followed a month later. The Diamonds were soon covering Little Darlin' successfully. The Diamonds were a Canadian pop group that evolved into a Doo-Wop group. The Diamonds' version reached number two in sales for eight weeks on the Billboard Hot 100. Billboard ranked this version as the No. 3 song for 1957.

Allmusic critic Stephen Thomas Erlewine argues that the Diamonds Little Darlin' is an unusual example of a cover being better than the original.
