Mildred Patricia Baena PISSED at Ex-Husband, Threatening to Sue Entertainment Tonight

Arnold Schwarzenegger's mistress, Mildred "Patty" Baena, is threatening to sue Entertainment Tonight over that interview with her ex-husband gave.

Claiming the show paid him "in excess of six figures to spew lies," Patty wants the network to cough up serious dough for supposedly slandering her.

Baena's ex, Rogelio Baena, called the whole child situation a "betrayal," insisting Patty led him to believe her love child with Schwarzenegger was his:

Patty's lawyer, Michael Saltz, fired off a letter to the producers saying E.T. ran the interview without ever doing any kind of research into Rogelio.

Her legal team says they can prove Rogelio always knew he wasn't the dad, and wasn't stunned last week like the rest of the world as he claims.

Rogelio was out of the country when Mildred Patricia Baena conceived, Saltz says, only returning to the U.S. after she was already knocked up.

The lawyers claim Rogelio was living in Colombia until E.T. paid to fly him "to the States to lie on television for a six figure paycheck."

Patty's lawyers tell "E.T." ... they believe "our client has been outrageously defamed" and demand an apology AND a retraction ASAP.
