Jen takes high road as John tells all

Jennifer Aniston’s pals were rolling their eyes over the weekend about John Mayer’s unofficial press conferences discussing the couple's breakup.

“Jen will never kiss and tell, but it’s she who ended the relationship,” a source close to Jen says. “(Mayer's) childish behavior only confirms she was right to dump him. Now he’s acting like a spoiled child. Expect Jen to behave like a lady.”

Mayer first explained his version of the breakup to an OK! magazine reporter, who quickly posted online that Mayer did the dumping. "I ended a relationship to be alone, because I don't want to waste somebody's time if something's not right,” Mayer told the reporter.

Yet Aniston's pal says the something that "wasn’t right" was Mayer’s behavior toward the press during the relationship. “He has a relationship with certain paparazzi (and) bloggers," the source said. “He tips them off. He loves the attention. Jen didn’t want to believe it was happening, but it was, and she has no tolerance for that.”  

Another issue: Money. “Jen was tired of paying for everything," said another source close to Aniston. “Cobwebs come flying out of (Mayer's) wallet when he opens it. John liked living like a movie star when he was with her. ... Jen would never say anything, but you could tell it irritated her.”

The sources close to Aniston say she isn’t going to make a statement about her relationship, despite their hunch that Mayer will continue to talk about it. “We’re talking about a guy who had a car waiting to take him home in New York, but he chose to walk so he could talk to the press (along the way). He’ll drag this out until there’s someone new,” says the source.

Presidential candidates pick top tunes
Senators John McCain and Barack Obama each picked out their top 10 favorite songs for Blender magazine. Their rather uninspired choices aren’t going to get them any DJ gigs, but the lists are interesting to pick apart.

McCain offers no evidence that he’s ever turned on the radio in this decade — songs by ABBA took two of his 10 slots, and other artists included Roy Orbison and The Platters.

Obama’s list, while more contemporary, does include “Yes We Can” by will.i.am, reportedly inspired by Obama's campaign. Creepy or cute? You decide.

Both candidates included a Frank Sinatra selection: “You’d Be So Easy to Love” for Obama and “I’ve Got You Under My Skin” for McCain. And speaking of McCain’s list, his addition of karaoke fave “Sweet Caroline” by Neil Diamond is oddly sweet.

‘Thunder’ roars at box office
I'm back on the horse, baby, after getting last week's box-office prediction wrong. As I predicted on Friday, “Tropic Thunder” topped all other films this weekend.

The flick's $26 million take fell short of very early estimates, which had the film bringing in close to $40 million. Nonetheless, the performance was good enough to keep Batman sequel “Dark Knight” from winning a fifth consecutive week.
