Yet another 'Jersey Shore' cast member is facing a lawsuit with a very hefty price tag. Mike 'The Situation' Sorrentino's former mangers are suing the reality star for $1 million.

What caused their business relationship to sour? According to TMZ, Gotham NYC Entertainment is claiming Sorrentino breached their contract when he fired them in May for "lack of performance."

The management company says the 'Jersey Shore' star failed to give them the required 30-day notice to fix any problems before he terminated their services.

Gotham says they have served as Sorrentino's managers since 'The Jersey Shore' premiered on MTV in 2009 and have helped him take "his career from relative obscurity to become an international celebrity."
