Speaking to the media at her make-up launch, Teigen also quipped that she has had extensive plastic surgery on her body and face but later clarified on Twitter that she was joking.
She shared a link to an article about her remarks and wrote: "Reminder to never ever joke, ever (I did do the armpits, no regrets except it clearly came back).
"You think I'd have this ass if I'd done extensive work?"
Meanwhile, Teigen also revealed that her anxiety over President Donald Trump and his policies is affecting her health and looks.
She tweeted: "so f**king tired of this manically insane, incompetent president and this dumpster fire administration I'm gonna have to go on another med.
"that is not a joke. I think I need to either up my dosage or talk to my doctor to "see what works for me" when the world explodes.
"Today I had a tooth shaved down because crippling anxiety makes me grind and rock my teeth on one side. I blame trump.
"I also had Botox in my jaw muscle to relieve tension from constantly clinching. I was not like this before. Pay my bill, POS POTUS (sic)."
