• Diddy and Cassie are secretly engaged? That's what the highly credible Star says. The rap mogul apparently told friends during son Justin's graduation from Horace Mann last month. [Star]

Eight bottles of perfume/cologne and the eight celebrities to blame for unleashing them on the naive public: Recognize the hands or the shapes of the bottles? The answer key after the jump.

Jennifer Lopez, new member of that oh-so-trendy and elite twinset pregnancy club, is continuing her fashionable legacy by deciding never to dress her mini-Marc Anthonys in the same designer outfit twice. As much as this news doesn’t surprise us, considering the international (national? not so much!) superstar’s notoriously highbrow taste in ridiculously pricey bling, we’re fairly sure where J. Lo got the idea. Even though the past few years have seen post-pregnancy slim faster Lopez awarded the #1 spot on many a prominent Best Dressed List in the glossies, her pre-glamour girl days were adorned with some of the most horrific ensembles ever to break camera lenses with their floppy fedoras, belly-baring latex bikini tops and, of course, her infamous frontless, transparent green monster worn at the 2000 Grammys. The top five outfits we’re grateful Lopez never dared wear twice, after the jump:

• Jose Canseco says Madonna once tried to marry him and have his baby, so she could give daughter Lourdes a Cuban sibling with great genes. He joins Dennis Rodman on the would-be Madonna baby-daddy list. [NYDN]

• Heiress Casey Johnson and Courtenay Semel, daughter of entertainment mogul Terry Semel, are officially dating. Casey is ditching plans to move home to Manhattan so she can stay closer to Courtenay in LA. [Page Six]

• This story is getting messier by the minute: It seems Alex Rodriguez's wife Cynthia has been in Paris where she's been hooking up with Lenny Kravitz while her husband may or may not be involved with Madonna. The only one not getting any, it seems, is Guy Ritchie. [NYP]

• Anne Hathaway dumped her scandal-plagued boyfriend Raffaello Follieri for all the obvious reasons: his legal troubles, the potential damage to her image, etc. Plus her parents despised him and her dad hired a PI to follow them around. [NY Post]

A new interview's out with P. Diddy, in which he discusses how he gets ready for an evening: a nice ball-waxing followed by heaps of cologne on his privates. Now it's time for everybody to go home. [Crazy Days and Nights]

• Late icon of conservatism William F. Buckley's duplex at 778 Park (also the last address of Brooke Astor) has gone on the market for $24.5 million. The 5,000-square-foot space (above) has four bedrooms, and 4.5 bathrooms; no extra charge for the lingering ghosts of Richard Nixon and Ronald Reagan. [Daily News, Barak Realty]

• Madonna's estranged brother Christopher Ciccone is writing a tell-all book about his sis, and it's supposed to be extremely graphic and "devastating." [Page Six]

• Is it really over between Madonna and Guy Ritchie? Madge has apparently hired England's toughest divorce lawyer, Nicholas Mostyn—the same guy who handled Paul McCartney's split with Heather Mills—so the answer looks like yes. [Holy Moly!]

• Beth Ostrosky loves sharing wedding details. Howard Stern's almost-wife says she and the shock jock will be inviting 150 guests to an October wedding in the city, and she'll be wearing a Marchesa dress that she's been discussing with Georgina Chapman. Oh, and the happy couple plans to adopt more dogs since Howard says he's not having any more kids. [Page Six]

What would happen if Hollywood’s most boy-crazy, sex-obsessed serial dater hooked up with Hollywood’s most lady-loving, satin-sheet-sex-obsessed player of all players? Well, for one thing we’d write about it. For another thing, the couple in question would most likely spend a sample evening locked in a private New York bar’s room, lorded over by a bodyguard just because they were so frisky they needed 20 minutes to themselves...that very second. Something else they might do? At a private concert thrown by Prince at his infamous party palace, they might escape immediately after feeding each other that always seductive aphrodisiac, bread pudding, into the “labyrinthe corridors leading to [Prince’s] basement” and do, well, what these two stars in question apparently do best: the dirty. Join us after the jump to put some faces to these places:

Didn't get to party with Diddy in Cannes last week? How unfortunate. You missed out on your chance to climb aboard the Maraya, the 177-foot yacht that Diddy chartered. A young, impressionable reporter for the Daily Mirror was lucky enough to land an invite, just in time to watch an assistant brush Diddy's hair:

• Longtime drug addict Tatum O'Neal was busted for buying crack near her Lower East Side apartment on Sunday night. [NY Post]

• Alec Baldwin lashes out at the family court system in his book, not his ex-wife Kim Basinger. He takes care of her at live party appearances: "My ex-wife reaches an almost sexual level of satisfaction when she's in a room full of high-priced lawyers." [Showbiz Spy]

• Naomi Campbell certainly made a splash in Cannes. After starting off her birthday taking ex-con Christophe Rocancourt—best known for pretending to be a Rockefeller heir and Oscar de la Renta’s nephew—to a movie premier, she capped off the night with a meltdown at Diddy’s yacht party and ended up leaving around 3 a.m. in a fit of rage. What was she so upset about? Who knows, this is Naomi Blackberry-in-your-face Campbell we’re taking about here. [NY Post]
  

Tabloid wars! When it comes to covering the stunt relationship between “bored” John Mayer and “clingy” Jennifer Aniston, two New York gossip columns have found themselves at odds over how well-behaved Mayer was over the weekend. The NY Post claims Mayer was dancing on tables at a local bar one night, while the NY Daily News covers his performance at a Foxwoods gig alongside Alicia Keys and Diddy the night afterwards. But one paper paints Mayer as an altar boy turning down “eager hot blonds” for the sake of monogamy, and the other makes Mayer sound like a vulgar womanizer. So which to believe?

After hearing that Billion Dollar Girl Miley Cyrus has added yet another name to her list of identities, we had to wonder how all this name-changing business is supposed to help an already-famous star's career. Cyrus, who was given the flashy title Destiny Hope Cyrus at birth, was nicknamed Smiley Miley as a kid by her achy breaky dad Billy and, guess what, it stuck. Now, AOL is reporting that Cyrus has officially changed her name to Miley Ray Cyrus, just like dad Billy Ray. But how have the most memorable mid-career name games fared when it comes to a celebrity's career? We took a look at a few of the most famous quick switches, and discovered it takes more than a flashy press announcement (and even a flashy new symbol) to inject a falling star with newfound fame...

Never one to miss an endorsement opportunity, Diddy has taken his partnership with Ciroc Liquor to a publicity-heightening new level. Citing not his fondness of earning Benjamins but rather his achy breaky heart as the reason behind this pragmatic endeavor, Diddy plans on launching a car service for celebrities who've had too much to drink at Opera and Les Deux and need a way home that doesn't involve cokepants or Vicodin swerves. More than anything else, we can't wait to see what the cars in question will be emblazoned with. We're envisioning that the rides will be pimped out in twead or pinstriped paint, with an oh-so-subtle 6x6 logo on the hoods stating "styled by Sean John." Which, if you think about it, would really flatter the drunken, passed out heads of Lindsay and Paris quite nicely. [Us]
