The Notorious B.I.G. & Faith Evans
Cause: Biggie and Faith were hip-hop royalty. But during their three year marriage, Big Poppa never really got the whole monogomy thing as he carried on a well known affair with Bad Boy artist Lil Kim. The relationship's stability was most likely not helped when Faith got dragged into the East Coast West Coast beef when 2Pac infamously claimed to have slept with her in "Hit 'Em Up."
Currently: The couple divorced before Big's tragic death. Since then, Faith has been raising their son as well as the two other children she has with record exec Todd Russaw.
