Last year the star hit back at ‘haters’ who expressed concern over her health and appearance.
The former child star – who boasts 1.1M Instagram/Twitter followers – wrote’Fun fact. This is my face. Not malnutrition no problems. Why do you have [to] hate? Get a calendar.’
The drama began when Michelle shared a snap of herself about to get her hair done at Tracey Cunningham’s Mèche salon in Beverly Hills.
A fan asked: ‘Michelle [you] look sick. [Are you] ok?’
Trachtenberg replied: ‘@cathy_critz explain to me how I look sick. Did you lose a calendar and not realize I’m not 14? I’m 38. How sad for you to leave such a comment.’
The next day, she posted yet another selfie with the defiant caption: ‘I’ve received several comments recently about my appearance. I have never had plastic surgery. I am happy and healthy. Check yourself haters.’
‘Nobody is talking about plastic surgery. They are talking about your liver shutting down,’ one follower wrote.
Another typed: ‘I really don’t think anyone was implying you had plastic surgery. We are generally concerned about you. Your eyes are yellow, your hair is [thinning] majorly, you look sick.’
‘People are just worried that your eyes are yellow and all your hair is falling out,’ another penned.
‘I think they are worried for your health.’
One follower wrote: ‘Anyone with yellow eye balls is not well and needs to see a doctor.’
