A statement Justin Timberlake made during a recent concert performance is turning heads, and Britney Spears is weighing in. During Timberlake's free show at Irving Plaza in New York City on Wednesday (on his birthday), Timberlake shared some choice words before performing his 2013 hit with Jay-Z, "Holy Grail." After Timberlake's comments made headlines, Spears wrote on Instagram on Thursday, "Someone told me someone was talking s*** about me on the streets !!! Do you want to bring it to the court or will you go home crying to your mom like you did last time ??? I'm not sorry !!!"
