Jennifer Lopez is back like she never left. Check out the promo shots she just released to go along with her new single "(What Is) Love?" Oddly enough, the song has been out since 2010, when it was included on the soundtrack to JLo's film "The Back-up Plan." Then it made its way onto her 2011 LP Love? and has been available online for some time. So who knows what's going on. At least we get some hot pictures!
