Kelis is dropping mad hints that her estranged husband Nas was stepping out on her before they split. The R&B singer, currently expecting her first child with the rapper, took to her Twitter page (@iamkelis) recently to share her thoughts on two-timers. In four successive tweets on June 4, she wrote:

1:41 p.m. This lovely day I would like to touch on cheaters. Super brief! Why be cowardly why not go after what you really want? Do peopl know what

1:43 p.m. They want? Probly not which just goes into know and respecting ones self. Also we can discuss whores I mean the nasty sub par tricks that

1:46 p.m. Participate in the cheating. Well let me say this, both parties that are gross. And in reality they deserve each other

1:47 p.m. All the scum bag coward husbands and the less then impressive sluts unite! You can all go down in flames together! Hooray!

Kelis filed divorce papers on April 30 citing "irreconcilable differences" for the break-up after almost six years of marriage. The battle for child support and custody of the unborn baby has already started, with Nas urging a judge to deny his ex cash for the child before it's even born.
