I don't know really what's really even going on in my life. To even assess that is... doesn't make sense because I have not made any comment."However, Bieber did manage a laugh as the radio DJ jokingly suggested he follow in Taylor Swift's footsteps and detail the break-up in a song.The singer has continued to keep quiet about the reported heartbreak, but he sent a telling tweet to fans after he was flooded with messages of support from his millions of devotees.He wrote, "Focused on the positive. 30 million Beliebers with me. I'm never leaving u because u r always there 4 me. Love u."
