THE NEXT time Taylor Swift writes a breakup song, it may not even be about her breakup.

PopSugar reports that after Robert Pattinson moved out of Kristen Stewart's house, Kristen went over to Taylor's Beverly Hills home to hang out.

An insider told Us magazine that Kristen "spent all day" there before returning home.

Tattle would not guess that those two would be tight, but Taylor knows breakups and Us says that both she and Kristen are pals with Taylor Lautner - Kristen co-starred with him in the "Twilight" films, Taylor "dated" him for a few months way back in 2009.

Eminem's song publisher is suing Facebook and its ad agency, claiming that they infringed the rapper's copyright.

In the complaint, filed Monday evening in Detroit federal court, Michigan-based Eight Mile Style contends that a Facebook ad that was broadcast online April 4 copied music from Eminem's 2000 song "Under the Influence."

The 30-second ad, dubbed "Airplane," was featured in a webcast by Facebook chief Mark Zuckerberg to announce Facebook Home, an interface for Android phones.

The complaint claims that the ad agency Wieden+Kennedy, of Portland, Ore., copied Eminem's music "in an effort to curry favor with Facebook by catering to Zuckerberg's personal likes and interests, and/or to invoke the same irreverent theme" of the song.

A Facebook representative declined to comment on the suit (but he did provide a paid list of other things the reporter might be interested in).

A version of the commercial featuring new music was posted to YouTube several days later, and the suit contends that the alteration "was an admission that Facebook knew it had infringed" on the Eminem song.

In an April 29 response, obtained by the Detroit Free Press, a Wieden+Kennedy lawyer argued that Eight Mile Style had no grounds to assert copyright, saying that the Eminem song passage had itself been copied from Michael Jackson's 1991 song "Give In to Me."

In the letter, attorney Guy Cohen attributed the writing and production of "Under the Influence" to periodic Eminem collaborator Dr. Dre, who Cohen contended "has a long, well-documented history of copyright infringement."

"Under the Influence" was, in fact, co-written by D12 and produced by the Bass Brothers, the Detroit duo who handled much of Eminem's work at the time.

TATTBITS

Carole King was awarded the nation's highest prize for popular music yesterday, receiving the Gershwin Prize for Popular Song, at the Library of Congress. She will be honored today by President Obama at the White House.

Last year, the 71-year-old King ("You've Got a Friend" and dozens of other hits) hinted that she might retire. Now she plans to introduce a new song for the Gershwin Prize that she wrote with the late Hal David titled "I Believe in Loving You." She plans to release it as a single next month in tribute to David.

Carol Burnett was named the winner of the nation's top humor prize yesterday.

The Kennedy Center for the Performing Arts said that Burnett will receive the Mark Twain Prize for American Humor on Oct. 20 in Washington. A gala performance will be taped and broadcast nationally Oct. 30 on PBS.

Burnett, 80, said she can't believe she is receiving the prize from the Kennedy Center.

"It's almost impossible to be funnier than the people in Washington," she said in a statement.

The Mark Twain Prize honors people who have an impact on society in the tradition of Samuel Clemens, better known as Twain, as a social commentator and satirist. Previous honorees include Bill Cosby, Steve Martin, Tina Fey and Ellen DeGeneres, who won last year.

* "The Bachelor" and "The Bachelorette" host Chris Harrison will again emcee the Miss America Pageant this September.

Harrison has hosted the telecast for the past four years.

The Miss America Organization said that he'll be joined by Lara Spencer, of "Good Morning America." Spencer served as a judge for the 2012 pageant.

The pageant will take place Sept. 15 in Atlantic City's Boardwalk Hall after six years in Las Vegas.

* This item has PR-plant fingerprints all over it, but British model Cara Delevingne, 20, reportedly turned down Leonardo DiCaprio, 38, at the Cannes after-party for "The Great Gatsby."

A source told the London Sun: "Normally all Leo has to do is look at a girl and they fall at his feet. Though Cara was having none of it."

We know the feeling.

"They spoke and he was pretty forward inviting her to a party back at his suite. They swapped numbers but that was it."

The source added, "He tried every trick in the book and apparently kept lunging for her . . . .

"Everyone is howling at the fact she actually knocked back the biggest actor in the world.

"She thought he was too forward and too old."

* This seems equally absurd: Harry Styles, 19, of One Direction, is reportedly being romantically pursued by Ke$ha, Rihanna, Rod Stewart's 33-year-old daughter, Kimberly, and other famous women.

Rod said in the London Sun that Harry has already spent the night with Kimberly.

Ah, to be young, famous, rich, well-coiffed and slightly talented.
