Jennifer Lopez's new documentary will shed light on her past relationships.

The 'Dance Again' singer says her tell-all programme, 'Jennifer Lopez: Her Life Her Journey', is going to look back at her three failed marriages and her famous boyfriends, which include Ben Affleck and P. Diddy.

Jennifer said: ''It talks about the relationships... because all of it's intertwined, especially when you're an artist. I think by the way, anybody in life, your personal life and your business life and the things that you do, it's all kind of intertwined and one affects the other and the decisions that you make and you can't tell the story - really tell the story - without going into those areas.''

The Latina bombshell - who has five-year-old twins Max and Emme with her third ex-husband, Marc Anthony - says even her close friends and entourage were shocked by some of the secrets she spills in the documentary.

Jennifer told website Access Hollywood: ''The people who are involved with the actual special, who have known me my whole life basically ... my family and people I've worked with from the very beginning, my producing partner, my manager - even when they watch the special they were like, 'Wow, I didn't know that about you.'

''It's gonna be, I think, full of a lot of little, interesting nuggets.''

'Jennifer Lopez: Her Life Her Journey' airs July 18 on NUVOtv in the US.
