• The title track of former Pussycat Dolls lead singer Nicole Scherzinger's debut solo album finds her equating love to physical pain. She explained to AOL Music why she named the disc after this song: "I came up with the title of the album 'cause at the time, there [were] only a few songs that I had written, to be honest with you - and 'Killer Love' was one of them. I wrote 'Killer Love' about a tortured love. Where you can't get enough of the love but it's not good for you. And I guess when the fans listen to the album, I want them to know that a lot of the music that I chose had to do with my past experiences and relationships, where I've lost myself many times. It's [about] being lost and broken and in a very fearful, dark place and the process [of] coming out of that. It's a very empowering album but it comes from a place of heartbreak."
