The rumor broke Tuesday that Parker had filed for divorce in Texas, but "Extra" has learned that she is the one who filed the papers.

"Extra" confirmed the actress found hundreds of text messages from another woman on Parker's phone. Reports say it is Erin Barry, the wife of one of the NBA player's former teammates, Brent Barry (pictured above).

There were also allegations Longoria's estranged husband also cheated on her earlier in the marriage with yet another woman, with whom he kept in touch via Facebook, sources say.

"Eva wants everyone to know, she's devastated by the rumors of Tony's infidelity. She loved her husband and is heartbroken about their split," said good friend, Mario Lopez. "But she's strong."

Longoria herself tweeted, "It is with great sadness that after 7 years together, Tony and I have decided to divorce. We love each other deeply and pray for each other's happiness."

Longoria has cancelled her Nov. 21 appearance at the American Music Awards and will spend Thanksgiving with friends, leaning on them and her "Desperate Housewives" castmates for support.
