"Demi was always insecure over the course of her marriage," a friend of the actress tells Us Weekly about Ashton's budding romance with Mila Kunis. "So yeah, it's hurtful that he's with someone he knew the whole time he was with her."

The former That '70s Show co-stars reportedly began a secretive relationship earlier this summer and have since made their pairing very public by walking around NYC in matching Chicago Bears jerseys and jetting off to romantic locations together.

"Demi is not psyched about Ashton and Mila," the friend continued, adding that the Two and a Half Men star is being "cheap" in their divorce proceedings.

"He's trying to get the best deal he can," the friend explained, saying that Ashton pockets $700,000 an episode for his role on the CBS sitcom.

Demi has faced a tough year, including a stint in rehab for rumored drug addictions along with an estrangement from her three daughters with previous ex Bruce Willis, Rumer, Scout and Tallulah.

"In the past few months, her life has totally spiraled out of control," says a friend of the Striptease actress. "Demi is beside herself over her fractured relationship with her three daughters, and she's heartbroken that Ashton has fully moved on. She's isolated, frightened and lonely."
