The model - who quit the ITV2 show after its second series - said that producers should not introduce too many new cast members.
"I don't think new characters are ever a good idea," she told New. "For example, they thought Georgina Dorsett would be a big character and she was hardly in it!"
Talking about the current cast members, she said: "I do think the viewers have seen enough of Mario Falcone and Lucy Mecklenburgh.
"We've seen a lot of this 'he's cheated, she's cheated' stuff and it has become a bit boring."
She added: "I also think Lauren Pope and Chloe Sims have run out of storylines.
"But I do hope they keep Sam Faiers, Joey Essex and Jessica Wright – they're my faves!"
Amy Childs recently stated that TOWIE cast members should watch their language on the show.
Lime Pictures is said to be currently working on an Indian version of the series.
