Conrad Hilton has been having a tough time lately.
The 21-year-old cousin of Paris and Nicky was arrested for screaming death threats on an airplane earlier this year, and he could be facing serious jail time.
Hilton says he would have killed a flight attendant if he hadn't by stopped by other passengers. Sources say Conrad copped a plea deal last month, but will probably still serve some time.
On top of all that, Hilton has apparently decided that he's heartbroken over a relationship that ended several years ago and his ex-girlfriend says he's now acting out in the scariest way possible.
Hunter Salomon - the daughter of Pam Anderson's ex and Paris Hilton's sex tape co-star, Rick Salomon - claims that she and Conrad broke up several years ago, but he just started making her feel uncomfortable last September.
Salomon says Hilton began showing up at her home at all hours and threatening to kill himself if she didn't take him back.
She says the final straw came last week when entered her home and "asked if he could please just see [her] before he killed himself."
He then instructed her to "get a restraining order, because he can't restrain himself."
Salomon filed for legal protection ASAP, and was granted a temporary restraining order in a Los Angeles court yesterday.
We'd say Conrad is like the Hiltons' version of Rob Kardashian, but at least Rob is only a danger to himself.
