The 34-year-old has apparently been told to lose five stone by September if she wants to secure the £100,000 deal.
A source told The Sun: "Gemma is known for loving her curves but she also knows how much money can be earned with a weight-loss DVD so is definitely taking the offer very seriously."
Reps for Gemma admitted she is 'in discussions for various projects'.
Last week GC confirmed she is no longer filming for The Only Way Is Essex, following reports that she threw a glass of champagne in a producer's face.
A spokesperson for Lime Pictures told the Mail Online: "We are currently not filming with Gemma Collins.
"She has taken a break from TOWIE to focus on some personal commitments."
If news of Gemma's fitness deal is true, she will follow in the footsteps of Geordie Shore stars Vicky Pattison and Charlotte Crosby, who have both released successful DVDs.
Charlotte's workout, 3 Minute Belly Blitz, became the fastest selling fitness DVD ever upon its release in December last year.
