It’s the Battle of The Disney Moms!

We hear Denise Jonas, best known as the mother of pop trio The Jonas Brothers, has effectively stopped speaking to Demi Lovato’s mom, Dianna DeLaGarza, after Dianna broke the Mouseketeer Code of Silence and went gushing on the Interwebs about the alleged romance between her actress daughter and crooner Joe Jonas.

While Demi — previously romantically-linked to Miley Cyrus’ older brother, Trace — took to her Twitter blog last month to refute claims that she has been secretly seeing her Camp Rock co-star, Demi’s mother seemed to confirm the Joe-Demi relationship whispers in an October interview with ZackTaylor.ca.

Denise Jonas is allegedly fuming over Dianna’s loose lips and has refused to speak to her fellow stage mom, according to spies close to both families.

“She was and still is very upset. The two families are very close and it was heartbreaking when [Denise] found out what Dianna had done. The two have not spoken much since, even though Dianna has apologized several times through phone and text message,” says a tattle. “Eddie (Dianna’s husband) has been working hard to fix this. They are planning a dinner all together soon to sit and talk things out.”
