The 32-year-old model was far from impressed when she received the message from her follower which urged her to grow back her locks because her new bob style did not suit her round face.

The follower wrote: "You look beautiful but you should grow your hair long again. Girls with round faces should not have short hair like that ... It makes your face look huge. Been there ... believe me ... LONG HAIR. (sic)"

In her reply to the comment, Chrissy wrote: "Honestly wow thank you because when I wake up each morning I wonder what @bcnjw would do and then I try to make her happy so this was a mistake on my part."

Since Chrissy's retort, the user has now closed down their account.

The curvaceous beauty is no stranger to impolite comments on social media and recently responded to a fan who asked her if she was pregnant again. 

Chrissy only gave birth to her second child, son Miles, four months ago so was understandably upset when one of her followers asked her whether she was expecting again after photographs of her at the 70th Annual Primetime Emmy Awards began to be posted online.

Taking to her Twitter account, she replied while quoting the tweet for all to see: "I just had a baby but thank you for being soooo respectful (sic)"

Chrissy has previously spoken about all the hurtful comments she gets from trolls online, admitting she can't understand what would compel someone to want to log on and post their vile barbs to her.

She said: "It's almost like f***ing walking up to somebody, or going to somebody's house, knocking on the door and being like, 'You're fat.'

"I don't know if they think they're ballsy or what. But if you're going to speak negatively about me, just do me a favor and don't tag me in it."
