Lauren, like the other cast members, reportedly gets paid just £50 per episode, to cover expenses, however the stars of the show are presented with numerous lucrative promotional opportunities and personal appearances in order to top up their bank balances.
Alongside co-stars Sam Faiers, Amy Childs and Mark Wright, The Mirror have reported that Goodger has collected tens of thousands of products from companies, eager for the cast to use them on the show, including the car from Kia.
However, Lauren has landed in hot water after the car has failed to appear in any of the episodes so far this series.
"Lauren's scenes in the Kia keep getting cut," a source told the paper. "She's used it while filming but so far it hasn't appeared in the show. Kia is demanding the car back because they had an unofficial agreement that hasn't worked out."
The insider added: "There's even some talk of them threatening legal action."
The news comes at the end of a difficult week for Lauren, who is facing a backlash after angry viewers accused her engagement to fellow cast member Mark Wright of being fake.
The Only Way Is Essex continues on ITV2 Sundays and Wednesdays at 10pm.
