PARTY FROM HELL

A friendship is put to the test as an ugly bust-up ends in tears

- 

They've been Block besties since week one, but sources say Leah and Kristy's friendship is about to be tested.

According to a TV insider, things come to a head at an explosive bash on Charming Street this week, where viewers will witness Kristy, 34, blasting Leah as they butt heads over sisters Eliza and Liberty, 34.

Shockingly, Eliza, 37, claims things got so out of hand that Kristy and Brett, 34, made the crew cry! "When you're telling people to get stuffed, when you're not treating people with respect, when tradies don't want to work with you, when you're making crew cry, it really tends to flick people away," she says. "They would kick and scream and yell, it wasn't a very nice environment to be in."
