While Tori Spelling stays quiet on rumors that her marriage with Dean McDermott is in shambles after he reportedly cheated, an insider told People magazine that she is "devastated."

"She's much more heartbroken than anyone realized. She's flipping out and is completely devastated. Remember early last year when the tabloids wrote something [about marriage troubles] and she blasted them on her website? Now she's not even doing that."

 Instead of slamming blog sites for reporting their alleged breakup, the friend that said that she is more focused on her children, Liam, 6, Stella, 5, Hattie, 2 and Finn who is 15 months old.

"No matter what, she's staying strong for her kids. She's all about her family. She worships those kids."

As far as what's next for Spelling, she is said to have idea how she's going to move forward.

The source added, "I don't know if she's strong enough to leave him right now with everything she's going through and four young kids. She could stay with him or not. God only knows."

Rumors that McDermott, 47, was not being faithful to Spelling, 40, sparked the day after Christmas when Us Weekly reported that his alleged mistress, 28-year-old Emily Goodhand, said they were having an affair.

She told the magazine they met on Dec. 6 in Toronto through friends while he was promoting his hosting job for Chopped Canada. She said McDermott invited her to his hotel room at the Fairmont Royal York Hotel.

"He told me he and Tori had a sexless marriage. I believed him."
