New York authorities have launched two separate investigations into the circumstances surrounding Wendy Williams‘ guardianship … TMZ has learned.

Sources connected to Wendy tell TMZ … Wendy just had an interview with Adult Protective Services, which also has made phone calls to people close to Wendy, asking about her living conditions in a New York assisted-living facility.

As TMZ reported … Wendy is locked on the 5th floor in the memory unit, where she cannot leave the floor without approval from an attendant. Numerous people connected to Wendy say she has no memory problems, and therefore, keeping her in that memory unit is inhumane.

We’re told Adult Protective Services called Wendy’s niece, Alex Finnie, asking a slew of questions relating to the various restrictions that have been placed on her in the guardianship.

In addition to APS, police paid a visit to Wendy at the facility, as part of a welfare check. An NYPD patrol car was parked outside the building on Monday morning.

Wendy, through people close to her, has asked both the NYPD and Adult Protective Services to launch an investigation into the guardianship.

Jessica Alba is one of America’s finest exports … she’s over in France for Paris Fashion Week and she’s looking absolutely stunning.

The actress looked white hot at the Gabriela Hearst fashion show … pulling up to her front-row seat with some sexy fishnets and a long, white coat.

She strutted her stuff in some black heels and accessorized with a black purse … with just enough cleavage peeking out from under her coat to bring in some more attention.

As we reported … Jessica is going through a divorce with Cash Warren, and she was the first one to pull the plug and file.

Since the split, we’ve seen Jessica lounging in Cabo, Mexico and getting an inspirational tattoo. Now, she’s taking her act overseas.

L.A. County District Attorney Nathan Hochman will hold a news conference Monday at 10 AM PT on resentencing the Menendez brothers … what’s curious is that resentencing is now irrelevant.

Sources say Hochman is expected to take a stand on whether Erik and Lyle should be resentenced, but the hearing that was scheduled for later this month has been pushed, and it’s unlikely it will ever happen.

As we reported, Cali Governor Gavin Newsom has taken the reins and asked the California Board of Parole Hearings to evaluate the Menendez brothers to determine if they pose a danger to society. The Board will issue its findings and send that on to the Governor, who will then determine if Erik and Lyle should go free.

Newsom just announced Monday he’s proposing new regulations that will make it easier for the Parole Board to assess whether prisoners are suitable for parole, which may be good news for Erik and Lyle.
