Let’s face it we all have one or two celebrity relationships that we are totally invested in.

However, when strife settles in, a high-profile marriage spells a heavily-publicized divorce if anything goes wrong.

While divorce can be amicable, not everyone is so lucky to have a reasonable ex-partner.

Oftentimes, divorce can get messy, especially when reputations and public image are at stake.

Scores of court battles tend to get petty and bloody pretty quickly when private family business starts to unravel.

Nevertheless, the turmoil kept brewing after that.

Brinkley found out her husband was cheating on her with his then-19-year-old assistant Diana Bianchi.

The couple separated and then divorced in 2008 in a whirlwind of events that left the model embarrassed.

Another court battle rapidly ensued, which left the “Vegas Vacation” star feeling embarrassed.

“She’s really upset and embarrassed that this is going back to court.

She absolutely did not want to go to court.

Peter is literally dragging her to court.”

The whole situation seems ultra petty and it’s hard not to see why Brinkley found it mortifying.

The kids are not always alright and can get caught in the crossfire.

Christie Brinkley’s grown-up and gorgeous kidshad to live through her very public divorce from Peter Cook.

The then-19-year-old wrote a detailed tribute, revealing that she had received counseling during that difficult time.

“My parents had just gotten divorced and I was so confused about everything,” the model penned.

“That was the start of a lifetime of friendship.”
