The former TOWIE star was clearly upset after seeing unflattering pictures of herself published this week, and took to the social network to vent her frustration.
Lauren tweeted: "Haven't eaten for three days not stopping until I get left the hell alone! I don't think I look like they make out but I'm going to be so skinny! (sic)"
After receiving a string of responses from fans (some worried about her and others accusing her of setting a bad example), she tweeted: "Sorry girls I stand by my ground for three years but now I want to be papped look pretty I feel so embarrassed what's happen this week that… I won't stop until they accept who I am the thought of food makes me sick I am going to be the slimmest girl in the industry that maybe they let me be sexy. (sic)"
Lauren, who is the owner of beauty brand Lauren's Way, added: "I've got 1 most successful brand in the UK which make me a millionaire but it's not good enough for the industry I'll always be the bad girl who has lived n learned now I'm going turn this upside down watch this space. (sic)"
All the tweets were later deleted and not replaced.
She later tweeted: "Sorry 4rant,V unlike me.Sometimes media pressure gets 2u & feels like cant do right 4doing wrong. Shouldn't have let it get me down. #PMA."
