Tori Spelling and Dean McDermott's marriage is rumored to be officially over, as a source revealed that the "Beverly Hills 90210" star has already signed their divorce papers without her husband's knowledge.

According to a report from Radar Online, the "True Tori" star's last straw was how her husband allegedly cheated on her during her recent hospitalization.

An insider revealed the alleged status of Tori Spelling and Dean McDermott's marriage: "When she was in the hospital [in late October], she heard about the pictures of Dean visiting a sex shop."

The daughter of Aaron Spelling was reportedly "mortified". The source said: "She couldn't believe he was back to his old games - while she was sick, no less - and thought he was cheating."

"She wants out. She's filled out the divorce papers," the source claimed.

The insider added that "Dean has no idea" that his wife has filed for divorce.

Tori Spelling and Dean McDermott's marriage problems seem to be taking a toll on the health of the reality star, and her mother, Candy Spelling, is said to be making things worse for her daughter.

According to a report from Hollywood Life, Tori Spelling and Dean McDermott's troubled marriage is the primary reason why the actress has been so skinny and sickly lately.

An insider said: "Tori is still stressed out about her relationship with Dean and as a result hasn't been eating that much."

"All the anxiety and uncertainty is still taking a toll on her health," the insider added.

An earlier report from Hollywood Life also pointed out that the 41-year-old actress' estranged mother, Candy Spelling, is still snubbing her daughter amid all her marital and health troubles.

A source explained: "Tori is crying out for help, she's crying out for her mom. She's always getting sick because she's so stressed out. She feels like her mom doesn't take her or her problems seriously."

The source added: "You would think that she wants Dean's attention, of course she does, however the main person she wants attention from is her absentee mom."

"Sadly, her mom just couldn't be bothered. It really is a shame," the insider told Hollywood Life.
