Faith Evans's Estranged Hubby -- STILL Her Manager

Can you really separate business from pleasure?  We think "NOT"! Good help is hard to find -- in fact, it's so hard ...  37 year old Faith Evans has decided to KEEP her estranged husband Todd Russaw as her manager ... despite filing for divorce from him last month, refusing to part ways totally.

According to The Detroit Press and public records, the IRS filed a $36,360 lien against Faith March 4 in New York.  Before that the IRS filed a $119,821 lien against her on February 16 . Which is only some of the troubled singer problems.  She has also asked the court to reject any claim of spousal support.

Faith tells TMZ, the divorce proceedings haven't changed a thing -- "Todd is going to be my manager still. I have a lot of personal things going on right now. My main focus is [my daughter] Chyna graduating from high school next week."

As we previously reported, Faith filed for divorce last month -- citing irreconcilable differences. The couple was married in 1997, but separated in 2005. Evans is asking for joint legal and sole physical custody of the couple’s two children, Joshua, 10, and Ryder, 4.
