Back in December, Emily Goodhand, 28, claimed that McDermott cheated on his wife with her.
“She’s much more heartbroken than anyone realized,” a friend tells the magazine.
“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.”
“I don’t think she even knows what she’s going to do right now,” the insider reveals.
“But no matter what, she’s staying strong for her kids. She’s all about her family. She worships those kids,” the pal says about Liam, 6½, Stella, 5½, Hattie, 2, and Finn, 15 months.
The couple was spotted together in Los Angeles on Thursday.
