Terius "The-Dream" Nash and Christopher "Tricky" Stewart penned this one for Janet. It's an ode to an ex-love that will always have a place in the heart. Newnownext.com asked Jackson if this was about a specific person such as her former husband Rene Elizondo Jr. The singer replied: "Yeah, but I'm not going to tell you who! They'll all think they're my greatest ex, right? (laughs) I think everybody has that - a 'greatest ex' - out of all your exes, your favorite. But that doesn't mean you're still in love with that person, or you wish to be with that person."
