Jennifer's career as a Billboard 100 pop singer began with her first single, "Crush". The song, written by Andy Goldmark, Mark Mueller and Cosgrove & Clark was initially played by KIIS-FM in Los Angeles in April, 1998 and went on to be the most-requested song on the radio station that summer. It ultimately became a Top 3 Billboard chart hit in the U.S., logged 17 weeks in Billboard magazine's Top 10 and went to #1 in Australia, Canada and New Zealand.
