The Marc Klasfeld-directed video, which premiered yesterday, centres on several couples, who went through difficult times after breaking up before starting new relationships, reported Aceshowbiz.
Clarkson, 32, also appears in the clip, looking gorgeous as she sings against a pink and purple backdrop.
'Heartbeat Song' is the first offering from the singer's 'Piece by Piece' album that is set for release on March 3 via RCA Records.
Marking her seventh studio effort, the follow-up to 2011's 'Stronger' will also include her collaboration with John Legend.
