“Secret Love Song” is a song recorded by British girl group Little Mix for their third studio album, Get Weird (2015). It features guest vocals from American singer Jason Derulo, who co-wrote the song with Jez Ashurst, Emma Rohan, and Tich. It was produced by Jayson DeZuzio. The group’s cover of Derulo’s 2015 single “Want to Want Me” inspired him to collaborate with them. “Secret Love Song” is a slow ballad comprising pounding bass and melancholic strings. The lyrics discuss unrequited and forbidden love, while Derulo’s verse details his personal experience of having an affair.
The song was announced as the third single from Get Weird in Ireland and the UK. It was met with mixed reviews from music critics, but reached number six on the UK Singles Chart. An accompanying music video was directed by Frank Borin and filmed in London near Tower Bridge.
