Rapper Eminem is convinced his home video movie that accompanied his recent hit MOCKINGBIRD is the best promo he'll ever make - because it makes him cry every time he sees it.

Eminem, real name MARSHALL MATHERS III, incorporates footage of him playing with his daughter HAILIE and niece LANEY before he became a star.

It also features clips of him and estranged wife KIM in happier but more desperate times, while he raps about the hardships of family life in Detroit, Michigan.

He tells BLENDER magazine, "By putting home-movie footage in the video, I think I laid it all on the table for anyone who didn't understand my relationship with Kim, or my relationship with my daughter.

"I get choked up every time I see the video. I don't think I'll ever make a video that will top Mockingbird."
