Ex-Raiders Cheerleader -- RIPS RAIDERETTE LAWSUIT ... They're Bitter Liars

A former Oakland Raiders cheerleader is BLASTING the ex-Raiderette who sued the NFL team ... calling her a "liar" who never really loved the sport.

TMZ Sports spoke with Nicole Rodrigues -- who cheered on the squad in 2003 and 2004 -- who insists she was always paid well during her time with the team.

"The Raiders, the whole organization, we're a family. That's the main thing ... they took care of us."

Not all of the former Raiderettes feel that way -- as we previously reported, a woman who called herself Lacy T. sued the team earlier this year claiming the team worked them like dogs and paid them less than minimum wage.

But Rodrigues is calling BS ... saying the women behind the suit are just looking for a quick buck -- and didn't appreciate the Raiderette experience

Bottom line for Rodrigues -- "I have zero complaints about how much I was paid."
