According to various sources, Spears had been rehearsing at the Forty Deuce in Los Angeles for a Wednesday show complete with backup dancers, but at the last minute, canceled.

“She wants to get back to performing on a small scale before she gets back in front of a big crowd,” according to a source, who says the singer apparently thought that the club, which is known for its burlesque shows, would be a good place for her first post-rehab appearance.

Despite repeated rehearsals, at the last minute, someone decided Spears wasn’t quite ready and the show was nixed, according to sources. It may be rescheduled.

The current buzz is that Spears will make a surprise appearance at one or more House of Blues in Southern California this week.

Making a clean breast of things
Kirsten Dunst was given a little more up top than nature provided for “Spider-Man 3.”

“I had to wear a padded bra on this movie, but I get it,” the actress, who plays superhero’s love interest Mary Jane, told the London Sun while promoting the flick.  “It’s okay. It’s part of the thing.”

Dunst wasn’t offended that the movie makers decided she needed a little extra padding. “I didn’t feel like it was sexist or anything. I embraced my Mary Jane boobs!”

Notes from all over
Dodgers fans aren’t Paris Hilton fans. The baseball aficionados at Dodger Stadium let out a loud “boo” when the partying heiress was pictured on the stadium’s Jumbotron.  . . . Boy George and Michael Jackson — on stage together at last? The producers of a 1980s retro show say they’re in discussions with the “Karma Chameleon” and “Thriller” singers. “Talks are ongoing with both acts to try and bring them to the event,” an organizer from Scotland’s Eighties Retrofest told the Scottish Daily Record.  . . . Justin Timberlake fans can do more than look but don’t touch. Concertgoers who were close to the stage for his Belfast concert were told they could “touch” but not “grab” the “SexyBack” singer, according to the London Mirror. “They were quite specific about what was and was not allowed. We’ve never known anything like it. It was hysterical,” a source told the paper, adding that some fans ignored the rule and ran onstage and grabbed the former boy bander, according to the source, who adds: “Justin looked a bit perturbed.”
