NAOMI FIRES MODEL FOR GOING OUT WITH HER EX-BILLIONAIRE BOYFRIEND

First he was spotted with an Naomi Campbell look alike in which we previously reported and now she slapped with the lowest blow of all.  The aspiring model seen frolicking with Naomi Campbell's ex-boyfriend has been fired by her management firm for 'unprofessional conduct' and an 'unacceptable work ethic'.  aka tacky b**tch!! 

British supermodel Naomi, 42, mentored Luo Zilin, a former Miss Universe China, on her reality show The Face earlier this year.  Luo, 25 - also known as Zi Lin - is reportedly dating Naomi's former love, Russian billionaire Vladimir Doronin - with the couple seen passionately embracing on the Spanish party island of Ibiza. 

And Neal Hamil, President, MIX Model Management NYC, confirmed that he ended the model's contract last week.

Hopefully Luo hasn’t triggered Campbell’s legendary temper. A source told the Daily Mail, “'It's fair to say that Luo and Vlad met through Naomi, it's really unprofessional of Luo and it's not great behavior on Vlad's behalf."

Page Six exclusively revealed that Campbell and the Russian billionaire put their five-year relationship on a break early last month. Shortly after the split, Doronin was spotted getting cozy on his yacht with bikini babe and Naomi-lookalike, Jazzma Kendrick.
