It's fairly common knowledge that Hollywood's biggest power couple, Brad Pitt and Angelina Jolie, have been on the rocks for the last few weeks. Neighbors and friends have heard them dissolve into screaming arguments bordering on Lohan-Ronson intensity levels, and recently a longtime friend of the couple told In Touch magazine that the tone in their home has been "cold. They're barely speaking."But what is causing these new conflicts? Apparently, the source of tension is Brad's latest confidant in his time of relationship turmoil-ex-wife Jennifer Aniston.

Friends of the former couple say that in the past few weeks, Brad and Jen have been talking frequently both on the phone and through texting. "It's a crazy position for Jen to be in-that of a shoulder to cry on," one of Jen's friends says about the increasingly personal conversations. "But she's excellent in a crisis, and she's happy to have Brad back in her life. "

Just how close are they getting? In Touch reported that on April 23, after visiting Angelina on the set of her new movie Salt, Brad headed across NYC to see Jen on the set of The Baster for their first one-on-one meeting in almost a year. "He pulled up in his black SUV," a friend of the former couple says. "He arrived on the opposite end of the set from where Jen's trailer was, and Jen snuck into his car. They drove around New York City together talking."

While Jen's rep denies the story, the friend says that the conversation was very personal, as Brad confided his relationship worries about Angelina and his fears about a possible breakup.

"[Jen] wants to be a good friend to him now," the friend says about the actress. "Brad's a mess right now, and that's hurting her."

So what does this newly kindled friendship mean for the ex-spouses? Jen admitted in Vanity Fair magazine that she will love Brad for the rest of her life, and Brad has also been wearing a necklace that Jen gave him for his birthday almost daily over the past few weeks. "Brad doesn't take that necklace off for days at a time. It's almost like he's trying to keep up a connection to Jen as his relationship with Angelina weakens."

Call me nostalgic, but is a reunion of one of my favorite Hollywood couples ever possible? This is one story I'll definitely follow carefully. Have a great summer, and until next fall, may Perez and E! be with you.
