WATCH: R Kelly's emotionally charged interview with CBS News


``Not true.'' That's how R Kelly describes the sexual abuse charges he faces in Chicago.  


The R&B star sat for an interview with CBS News -- in which he denied charges that he sexually abused four females, including three underage girls. 


An agitated Kelly challenged interviewer Gayle King when she noted there have long been rumours about his having sex with underage girls. 


The singer insisted, ``whether they're old rumours, new rumours, future rumours, not true.'' 


Asked if he had held women against their will, the singer replied, ``That's stupid!'' Parts of the interview aired last night with more to come on today's and tomorrow's editions of ``CBS This Morning.''
