Taylor Swift is prepared to go to war with a website called Celebrity Jihad ... claiming she was wrongly identified in a "leaked" nude photo ... and now she's threatening to sue their asses.

The photo in question features a topless woman who bears a resemblance to Swift under the headline, "Taylor Swift Topless Private Pic Leaked?"

Swift's lawyers are pissed -- and fired over a letter to the site demanding it take down the post immediately ... or else she'll sue for trademark infringement.

In the letter, Team Swift says the site contains, "false pornographic images and false 'news" about the singer.

A rep for the site tell us the blog is considering its options. Swift's people had no comment.

Despite the rain, Taylor Swift paid a visit to John F. Kennedy's Eternal Flame grave site at Arlington National Cemetery in Washington D.C. on Wednesday.

The 21-year-old was in the nation's capital for the latest stop of her Speak Now World Tour.

We've slipped some subtle differences into these crafty photographs -- can you spot 'em?


**HINT -- There are THREE differences in the above photograph!**

Jake Gyllenhaal went cruising with rumored girlfriend Taylor Swift in L.A. on Thursday.



The 29-year-old is definitely the one in the driver's seat in this relationship.

After being spotted getting cozy at a coffee shop in Tennessee this weekend, rumored couple Jake Gyllenhaal, 29, and Taylor Swift, 20, enjoyed another intimate cup of joe at the Frothy Monkey in Nashville this morning.



Sources tell us the duo have been in the past several mornings and "looked like they were more than friends" ... whatever that means.

Jake & Tay really know how to get their hearts racing.

Kanye West went on another trademark rant last night -- unleashing about everything from Taylor Swift to George W. Bush ... and even took what seemed to be a serious shot at Matt Lauer.



During his concert in New York last night, Kanye brought up the "Today" show drama again (and his allegations that Lauer ran a clip from his interview with Kanye out of context) -- and made the following comment:

"Matt Lauer's not a bad guy I'm sure ... but if you are a child that's being abused by your parent ... or you are a girl being abused by your boyfriend ... the greatest win that you could ever have is for that person to hit you in public. You SEE! YOU SEE! I TOLD YOU!"

For the record -- Matt and the "Today" show insist they did NOTHING wrong.

As for Kanye, he also ranted about the infamous Taylor Swift moment at the VMAs -- saying, "If I wasn't drunk, I woulda been on stage longer."

He continued, "Taylor never came to my defense in any interview .. and rode it and rode it."

Check out the clip -- pretty crazy stuff.

Here's 20-year-old country darling Taylor Swift rockin' one of  Kim Zolciak's old wigs at the American Music Awards last night (left) -- and A-list porn diva Jenna Jameson back in 2007 (right).


Scandalous.

We're just sayin'.

Little blonde country darlings Taylor Swift, 20, and Miranda Lambert, 27, both twanged at the same event in Nashville on Tuesday.



Question is ...

Taylor Swift hit a Target department store in Harlem yesterday -- but she wasn't there to shop ... she was there to sell!


With a giant muscle-bound entourage, Swift rolled in for an album signing event Monday afternoon ... the same day her new John Mayer-bashing CD hit the shelves.

The event turned out OK ... but Beyonce's album signing at Macy's in 2006 was one of the BEST OF ALL TIME! 

Wearing a full face, "Seinfeld"s puffy shirt, a naughty schoolgirl mini, lacy stockings and a pair of post-apocalyptic knee-high pirate boots, glam country darling Taylor Swift made her way to a fashion show in Milan on Monday.


What a doll.

Wearing her grandmother's high-waisted 1950's two-piece polka dot bikini, country sensation Taylor Swift attempted to tan her ivory skin on the beach in the Bahamas this weekend.



The 20-year-old is very mature for her age.
