The track will be released on March 10 in the UK as the lead single from her upcoming second studio album.
"['Boomerang' is] just a fresh song, a fresh sound with energy behind it - on this single and the whole album, so it's fun," Scherzinger said of the song.
"I know it's so cheesy but I actually have a song on the album called 'Fun'. I'm not gonna be like, 'Oh it's just deep'.
"I mean there are some songs like that, but for the most part I think [fun's] what we need at the start of the year, right?"
'Boomerang' was produced by will.i.am. The video was shot late last year while she was judging The X Factor.
Scherzinger recently revealed that she hasn't been asked back for this year's show yet.
Her last album Killer Love peaked at number eight on the UK album chart when it was released in 2011, producing hit singles 'Poison', 'Don't Hold Your Breath' and 'Right There'.]
