NEW YORK -- In a lengthy social media post, Justin Timberlake says that he wants to apologize to Britney Spears and Janet Jackson “because I care for and respect these women and I know I failed.”“I’ve seen the messages, tags, comments, and concerns and I want to respond. I am deeply sorry for the times in my life where my actions contributed to the problem, where I spoke out of turn, or did not speak up for what was right.
