It's been a rough year for Tori Spelling -- and it might be getting even worse. After the reality star has weathered her husband Dean McDermott's alleged cheating, the loss of their retail store and ongoing legal issues related to a $60M lawsuit, Breaking Celebrity News has learned that she could be hit with her biggest hit yet -- a tell-all from McDermott's ex-wife!

McDermott hooked up with Spelling in 2006 while he was still married to Canadian actress Mary Jo Eustace. And though she was relatively tight-lipped through recent rumors that McDermott had cheated on Spelling, she recently hinted that might be changing.

"Waiting to hear about an amazing project," she tweeted coyly on February 24. "Spilling all my secrets …."

Eustace spoke out briefly after McDermott entered rehab, admitting, "My main concern at this time is the well-being and health of the son Jack,15 we share. I wish Dean only the best in his struggle to overcome the demons he has been wrestling with for many years, so he can become the father and the man I  know he wants to be."
