'Real Housewives of Miami' Star Alex Echevarria Sued By Hoity-Toity Club ... You Owe Us $160k!!!!

"Real Housewives of Miami" stars Alexia and Herman Echevarria LOVE to live the high life in Miami -- they just don't wanna pay for it ... this according to a primo country club that is suing them for $160,000 in unpaid membership fees.

Fisher Island Club recently filed a lawsuit against the couple in Florida court -- claiming Alexia and Herman dropped $250,000 (yikes!) to become members back in 2006. They claim that at some point, the couple stopped paying their monthly dues ... and now owe $166,916.49.

FYI -- Fisher is an crazy exclusive club in Miami where well-off members rub elbows on their own private beach, golf course, dining club and spa.

According to docs, Alexia and Herman opted for the most expensive membership -- and besides the $250k to join, they were required to cough up $18,300 per month in dues.

The club says it keeps billing the couple, but no cigar. It's demanding the dues plus interest. 

A judge has yet to rule.
