[lastfm link_type="artist_info"]U2[/lastfm]‘s bassist Adam Clayton has apparently been keeping a big secret — he’s a dad! The 50 year-old rocker surprised fans last week when they got word that Clayton is the proud father of a one year-old son. Sources close to Clayton say that he is delighted to have finally joined his bandmates in fatherhood.
