Tori Spelling growing closer to mother Candy Spelling after husband Dean McDermott seemingly distanced himself from their 17-year marriage.

A source tells PEOPLE Candy has been instrumental in helping Tori, 50, navigate this difficult time. “She has given Tori assurances that her and her kids would absolutely be taken care of and there should be no financial insecurity moving forward,” the insider says.

Candy, 77, is also stepping in as a source of comfort for her five grandchildren. “The children love their grandma because she spoils them and gives them the best treats! The children are Candy’s whole world, and she loves spending as much time with them as possible,” they say.

And though mother and daughter were formerly estranged, the insider affirms that the pair's "relationship is the best it has ever been. The only regret Tori has is that she held on to her resentment for so long and they lost a lot of time, but she hopes to make up for it now.”

A second source confirmed Candy has been acting as something of a counselor for when and if a divorce from McDermott, 56, plays out: “Candy is helping with her divorce and referring attorneys. Candy wants to make sure the kids will be OK.”
