Because we think it's more than a little CLEAR after last night that Selena Gomez ain't missing that - or anything else about you - AT ALL!
Not that she needed to explicitly state it, mind you! She let the heartbreak and anger of her musical predecessors - and contemporaries - speak for her!
The singer was spotted looking pretty glum two days ago as she arrived in New York City for last night's UNICEF charity concert with her band, The Scene, and clearly, channeled all of that break-up sadness into one HELLUVA set!
In fact, the former Disney starlet not only responded to her ex's November rendition of Justin Timberlake's Cry Me A River with her very OWN version of the track, but she also paid tribute to her bestie - and confidante - Taylor Swift by bellowing out her very own break-up anthem, Trouble!
