J.Lo and Casper fake-out!

Jennifer Lopez and Casper Smart broke up last June. Except they didn't. Or they did, says TMZ, but just as a business move. Both were doing flicks (she: Boy Next Door; he: Street) and felt they'd be a sexier sell as "singles." Such moves have a long history in Hollyvoid, where stars pretend to be likin' or not likin' - heck, they'll be moss, if it'll sell tix.

Dot dot dot, etc., etc.

Drea De Matteo, who played Adriana La Cerva on The Sopranos, has, or had, a pad in the building that exploded Thursday in Manhattan. She's OK. . . . Rumor Mill Grinding #44,213: Taylor Swift, dating Calvin Harris? (Query to Webster's: Does the noun dating even mean just dating anymore?) He says she's not his type. But they've been seen together. So, c'mon, it has to be, like, totally true. . . . Rumor Mill Grinding, #44,214: Once they said Blake Shelton was steppin' out on Miranda Lambert; now it's vice-versa.

And: Just try not to laugh at this Foxnews.com headline (we couldn't keep the giggles at bay): "Britney Spears is learning pre-algebra to keep up with her sons." . . . Sam Taylor-Johnson, director of Fifty Shades of Grey, says she won't direct any sequels. . . . Most Twitter feuds are as empty as balloons. Example: The Twit-tiff between Kylie Jenner and Blac Chyna over KJ's alleged dalliance with BC's partner in procreation, Tyga. Shade-throwing, y'all!

Last lap: Betty White tells Oprah Winfrey her biggest regret in her 93 years is that she waited a year to say "Yes" to a proposal by Allen Ludden. They were wed from 1963 until his death in 1981. . . . Gareth Neame, executive producer of Downton Abbey, said Thursday that next season will be the last for the historical soap opera. . . . Oisin Tymon, the producer slugged by now-fired Top Gear host Jeremy Clarkson, says he won't press charges. . . . Lena Dunham, brazen edge-treader, wrote a New Yorker piece, "Dog or Jewish Boyfriend? A Quiz." Clues such as: "He doesn't tip. And he never brings his wallet anywhere." She's now being called anti-Semitic. Ironic, since she's matrilineally Jewish.
