This song finds Adam Levine begging a femme fatale to come back to him from her new boyfriend. The Maroon 5 frontman penned the song with guitarist James Valentine and bassist Mickey Madden. Valentine recalled to Ultimate-Guitar.com
: "One day I was talking to Mickey Madden and it was like, 'Let's just come up with a couple song titles' and he came up with the titles 'Ladykiller' and 'Fortune Teller. He said, 'Those sound like good sounding names.' We were on the road and I'm always sort of tinkering around with riffs and ideas and track ideas in Logic Pro. I looked at 'Ladykiller' and I ended up sort of writing a song with first-draft lyrics and then played it and Adam was into it and he added to the lyrics and tweaked a couple of the melodies to suit more of where he would sing it."
