Songfacts®:

• This club tune is the first single to be released by British/Irish girl group The Saturdays mini album, Headlines. The set was released to bridge the gap between their second and third albums. According to the quintet's record label, "The bittersweet lyrics are an ode to a lost love."
• The song's music video was shot in Malaga, Spain at the end of May 2010. Singer Vanessa White told BBC News: "Every time we'd turned round, our dresses would get stuck to our legs! That was a nightmare. It was either that or slipping over."
• The song is about a troubled relationship. Vanessa told BBC News: "It's about being in a relationship where the passion has gone - so you're missing that spark. It's quite deep, actually, for a pop song."
• The girls also sung about troubled relationships on their previous singles "Forever Is Over" and "Ego." Vanessa explained to BBC why they so often choose to sing about such matters: "I guess we always want to relate to what our fans are going through and everyone has been in a relationship like that.
  That's why I really like doing Missing You acoustically. When we use the full backing track, we have to do all the dance moves, but when it's acoustic you can really get into the emotion of the song."
