Carmen Electra may love rock 'n' roll, but it looks like she didn't put another dime in Joan Jett's jukebox. The bombshell, 34, is pooh-poohing whispers of a sapphic-tastic hookup with the 46-year-old rocker, whom she's been palling around with in recent months. "They are just friends," Electra's rep tells Us Weekly. The denial comes just days after Star declared them "in love" and claimed they plan to turn up together at the forthcoming Dinah Shore golf tournament, where, says a snitch, the former Mrs. Dave Navarro would "drop a huge bomb ... that's going to surprise a lot of people." Electra, who became buddies with Jett after she appeared in one of her videos last year, is scheduled to perform at the event, but Jett will reportedly be a no-show. Meanwhile, the London Daily Mirror claims Carmen has a "new man in her life," identifying the lucky fella as an agent named Alberto.

After 28 long, arduous days inside the swanky, spa-like Promises rehab facility, Britney Spears has been released back into society, where the "false tabloids" are already abuzz with chatter that a big chunk of her savings could end up in the baggy, saggy pants of soon-to-be ex-hubby Kevin Federline. TMZ.com, however, is laughing off claims that K. Fed will skulk away with close to a $20-million divorce settlement, saying an "airtight prenup" will limit his take to about $1 million (feel free to insert a "chump change" joke here). As for arrangements surrounding Sean Preston, 18 months, and Jayden James, 6 months, who have been in the care of their dad during their mom's meltdown, Britney and Kevin will continue to divvy up custody 50/50. "Kevin and his divorce attorney, Mark Vincent Kaplan, are very happy and cautiously focused on Britney's rehab follow-through," an insider tells People. "[But they] are not about to return custody to Britney as a reward for her going through Promises." K. Fed, explains the source, will consider giving Spears "increased custody [after] demonstrating that she is living the life consistent with the best interest of her children." By the by, someone who's dealt with Britney postrehab is paying her a backhanded compliment, telling TMZ that she's now "nice as well as reasonable."

The busy lips of self-professed "make-out king" Pete Wentz apparently don't get a break even when he's on vacation. Us says the eye makeup-addicted Fall Out Boy frontman recently enjoyed a "hush-hush" Mexican sojourn with sometime squeeze Ashlee Simpson. "She really likes him," an Ashlee mole tells the mag. Last month, you'll recall, Wentz callously dismissed rumors linking him to the refurbished warbler, telling Rolling Stone, "Maybe in a different universe, we'd be some hot couple, but not in this one." But that attitude didn't stop him from getting hands-on with Simpson during a night out at Los Angeles hot spot Hyde on March 12. "He massaged her back and played with her hair," a spy tells Us. Ashlee, however, should probably keep her options open. Says a Pete pal, "They aren't that serious."

In related news, Ashlee's big sister Jessica remains in the throes of schmoopiness with John Mayer. E!'s Marc Malkin says the well-coiffed couple joined about a dozen of their closest pals earlier this week for a middle-of-the-night chow-down at a Los Angeles eatery, where they munched on mac-and-cheese, frozen hot chocolate and buffalo wings (no word on whether Jess entertained the crowd by reenacting her classic "I don't eat buffalo" moment from "Newlyweds"). Simpson and Mayer, who just returned from a PDA-crammed jaunt to Rome, were "very into each other" during their two-hour carb-fest, says an eyewitness.

Lance Bass appears to be on the rebound from his breakup with Reichen Lehmkuhl. The New York Daily News spied the former boy-bander "getting friendly" with an "L.A.-looking blond guy" at a Manhattan bar Tuesday night.

Gisele Bundchen insists she's not mothballing her skimpy Victoria's Secret lingerie for roomy maternity-wear anytime soon. "It's crazy how people can make up these stories," she huffed this week on the Spanish TV show "Corazon de Primavera," responding to rampant rumors that she's carrying the spawn of boyfriend Tom Brady. "I'm not pregnant and I'm not planning to be pregnant anytime soon. I have so many contracts to do, so many projects." The Brazilian bombshell's denial puts an end to the many jokes in the "Brady Bunch" oeuvre, which were sparked by the quarterback's already impending bundle of joy with ex-girlfriend Bridget Moynahan. As for Gisele, she says a bun in the oven "is just something I don't want now -- it's something for the future." Besides, she says, "I'm 26 years old ... Why would I have a baby now?"
