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.”

“There’s been a lot of rumors lately that I’m dating one of my best friends Joe. I can promise my entire career that I am not. We’ve NEVER dated,” Demi Tweeted. “He’s incredible, but we don’t have feelings for each other in that way. I love you guys, and I wouldn’t lie about that. It’s unfortunate that some people out there are so desperate for attention that they have to make up gossip to keep their site alive. But that’s how this whole city works I guess. It just makes me sad that people are that mean in this world.”

That’s a lot more than 140 characters, Demi. We get the picture.

“No edit. No make up. Raw,” Demi wrote beneath the image.

As most diehard Demi fans already know, the bubbly 16-year-old got her start as a child star alongside bestie Selena Gomez on the classic PBS show Barney. So it didn’t take Jimmy look to convince Demi to rock out to a “death-metal” version of the show’s cheesy theme song.

Can’t say I blame the girl. I wouldn’t want to claim that either. Yuck…

“Demi is one of my good friends and I definitely became very, very close with her in the past few months, and it’s something I really wanted to make work. But unfortunately, we both have very busy schedules – we’re both on tour right now,” Trace told PEOPLE Tuesday. “I’m always on the other side of the world and so is she, so it just seemed like something that can’t work out at this time.”

The four-year age difference between the fully-legal Trace and underage Demi also strained the relationship.

“…She is a lot younger than me,” the 20-year-old says of his ex, who is 16. “When someone is that much younger, you’re looking for different things in relationships. Maybe when she’s older and we’ve both matured, we’ll be looking for the same thing and it can work out.”

“We gave it a shot and that’s all you can do.”

Despite the split, Trace insists there are no hard feelings between he and Demi.

“Every time I hung out with that girl or talked on the phone with her, it was amazing. She’s someone I can totally relate to.”

Disney’s Camp Rock 2 The Final Jam will start shooting later this summer for a debut on The Disney Channel next year.

Pop trio The Jonas Brothers and Disney starlet Demi Lovato are headed back to Camp Rock in the sequel to last year’s top-rated cable TV movie, The Hollywood Reporter has learned.

The brothers return to their beloved Camp Rock only to find that a large number of students have moved to nearby Camp Star. In a Romeo & Juliet-inspired twist, things get complicated when Nick’s character falls in love with the daughter of Camp Star’s owner, played by 17-year-old classical pianist Chloe Bridges.

The original Camp Rock has been watched by an audience of more than 146 million people worldwide.

Demi Lovato proved herself to be a real trooper after she laughed off a stage fall during a concert in Philadelphia over the weekend.

The Disney star, 16, was left a bit red-faced when she stumbled down a flight of stairs onstage during a performance of “Next To Men” at the Saturday evening show.

In an interview with MTV News Thursday, Disney star Demi Lovato insisted that she is not dating Trace Cyrus, the 20-year-old brother of Demi’s frenemy Miley Cyrus.

“I’m single! Yeah, I’m definitely single,” she told MTV News. When asked who she would love to date, she left the answer open: “I can’t say!

Despite Demi’s denial, celebrity informants at The Globe claim that the 16-year-old is not only dating the Metro Station guitarist, but she’s doing so to the displeasure of his famous sister.

“Miley hasn’t said anything to Demi’s face, but behind her back she’s telling people that she doesn’t like the relationship one bit,” a spywitness spilled on the pages of the tab this week. “I think she’ a little jealous of the special bond between the two and feels left out,” says the source, who adds, “She’s also mad because she thinks Demi is somehow horning in on the family.”

Singer/actress Demi Lovato has accused her estranged father of lying about reconciling with her and her two sisters in recent interviews with the media.

“We still are (estranged). It’s not exactly how he made it out to be. It didn’t have the fairy tale ending that he portrayed. The last time I talked to him was two years ago,” the 16-year-old clean-cut Disney star explains.

The elder Lovato left the family when Demi was only two, the actress insists she tried to maintain a relationship with her dad but says he made their relationship extremely difficult.

“You try to have faith in somebody, even when you’re the last person that believes in him. But when somebody lets you down after you’ve been the only one there for them, and so many times, you don’t know what to do.”

“I had to cut off all connection. It was hurting me too much,” Demi explains.
