Luo Zilin 'The Face' Contestant FIRED [PHOTOS] Naomi Protege Caught Hooking Up With Ex Boyfriend Russian Billionaire Vlad Doronin

Is a hook up or one nightstand with a married man ever worth your career?  "The Face" contestant and 2011 Miss Universe China contestant, Zuo Zilin learning that the hard way. Zuo was recently dropped by MIX Model Management, after photos of her hooking up with mentor supermodel Naomi Campbell's ex boyfriend, Russian billionaire, Vladamir Doronin surfaced all over the net.

Luo appeared on the Oxygen reality series, "The Face," a modeling competition hoted by Nigel Barker, and featuring supermodels Coco Rocha, Karolina Kurkova, Kate Upton,and Naomi Campbell as coaches. Luo was on "Team Naomi" all of Season 1, so it came as a shock when photos of her making out and straddling Naomi's boyfriend surfaced.

MIX Model Management NYC ended her contract last week, according to the Daily Mail. Neal Hamil, President of MIX Model Management NYC confirmed that Luo was fired for 'unprofessional conduct' and an 'unacceptable work ethic'.

According to The YBF, Naomi hasn't spoken out about the backstabbing model, Luo's former "The Face" competitor and co-star Jocelyn Chew tweeted, 'I'm completely shocked/disgusted W my 'teammate' Zilin. Never judge a book by it's cover. #truecolors love you @naomicampbell '

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."  Doronin is still married and quite the ladies man, he was also seen cuddled up with a Naomi Campbell look alike, Jazzma Kendrick last month in Miami.

Luo was the last girl standing on Team Naomi and was a runner-up on "The Face."
