Camille Grammer's Ex-BF Sues Over Fabricated 'Assault' -- She Ruined My Life


11:00 AM PT -- Camille's lawyer tells TMZ, "We are delighted that he filed a lawsuit because we are already in the process of filing a civil lawsuit against him to pay for the damage he has caused. We look forward to court, where we will introduce forensic evidence clearly establishing his liability. It is surprising that someone who committed an assault would actually sue the victim."

's ex-boyfriend thinks she should write reality TV -- because the "assault" she concocted and then accused him of last year was worthy of an episode of "Real Housewives."

Dimitri Charalambopoulos has filed a lawsuit against Camille, accusing her of bold-faced lying over a blowout fight they allegedly had last year.

You'll recall, Camille claimed Dimitri beat her to a pulp in a Houston hotel room and even ripped out her hair.

But according to Dimitri's lawsuit -- filed by his attorney, Guy Fisher -- there was no fight. He claims she baselessly accused him of cheating and he immediately left the hotel room ... at which point Camille faked the entire melee, smudging her make-up and even pulling hair from her hairbrush to scatter around the room.

And under the category "salt in the wound" ... Dimitri claims she made her bogus claims after he cared for her post cancer surgery, doing everything from helping her shower to "draining her catheter bag."

Sources tell us ... Dimitri thinks it's the most fantasy filled novelesque manner that the screenwriters for 'Housewives of Beverly Hills' would envy.

As we reported, the felony assault charges that followed were dismissed this week due to lack of evidence. Dimitri insists the damage is done ... his life has been devastated by Camille's lies.

He's suing for defamation, malicious prosecution, fraud and more.
