Wendy Williams Has Completely Cut Off Estranged Husband Kevin Hunter

Wendy Williams is taking several steps -- professionally and personally -- to erase her estranged husband from her life, and she got the ball rolling even before serving him divorce papers.

Sources close to Wendy tell TMZ ... she's totally cut Kevin Hunter off from her money and has hired a team to ensure all of her finances are secure. We're told she's separated their funds and created new accounts ... a process that began before she filed for divorce.

Wendy's officially locked down her own place in Manhattan, as well. Our sources say she signed the lease on her new home a few weeks ago and has already paid rent for the next year.

She and Kevin previously lived together at their home in New Jersey. That's where that weird story went down in January ... when, as we told you, cops conducted a welfare check on Wendy.

As for business matters -- we're told Wendy waffled over whether to keep a professional relationship with Hunter, but ultimately decided to cut all ties. She's currently looking for a new manager.

Sources connected to Kevin tell us he hasn't received any money from the show following his departure. Not yet.

We're told he's known as a pretty savvy business guy, so show execs fully expect he'll insist on some kind of exit package.
