Taylor Swift & Harry Styles

Taylor Swift doesn't just write breakup songs about her ex-boyfriends ... she talks SMACK about them during award shows ... and last night, she got caught. On camera.

It happened when One Direction took the stage to present a Moon Man at the MTV VMAs for Best Pop Video.

FYI -- Taylor used to date Harry Styles (they broke up in January) ... but apparently, she's still harboring some resentment -- 'cause as the band rambled on, the camera cut to Swift ... who leaned over to Selena Gomez and mouthed the words, "SHUT. THE. F**K. UP."

There are people out there who swear Taylor wasn't cussing -- that she was saying the words, "Sorry for my arm."

Those people are stupid.

If there's one thing Harry Styles didn't get enough of while dating Taylor Swift ... it's clam -- because that's pretty much the first thing he ate following their breakup ... and TMZ has the pic.

The "One Direction" singer -- who just ended his record 2-month relationship with T. Swizzle -- was in Queens Sunday night, when he got a hankering for some Italian ... and swung by the famous Don Peppe's with a pal.

We're told Harry appeared extremely chill throughout his meal -- happily noshing on veal parmigiana, shrimp luciano over linguini, and his main course ... a steaming pile of clams.

Taylor Swift and her future ex-boyfriend Harry Styles are making the most of their time together before the breakup -- and hit the slopes for a little ski vacay in Park City, Utah.

The adorable pics were snapped Friday at the Canyons Resort ... when TSwift and the One Direction star decided to take a little lunch break in-between shredding the gnar.

We can't wait to see how this all plays out in a song ... but what rhymes with Utah?

Like a good elder girlfriend, Taylor Swift, 23, chaperoned her current boyfriend Harry Styles to get his latest tat in West Hollywood on Tuesday.

With Taylor clinging to his side, the 18-year-old One Direction singer got an image of a huge ship inked on his left upper arm at the ever popular Shamrock Tattoo.

While Harry is no stranger to body art, he's so far managed to avoid getting Taylor's name etched permanently into his flesh.

Pretty funny -- considering the bad boy in Taylor's new music video "I Knew You Were Trouble" gets a very similar tattoo ... and the song's all about how he broke her heart (surprise).

As we previously reported, the two have been spending a lot of time together lately ... and took a romantic stroll around Central Park earlier this week.

If history repeats itself, "Haylor" will enjoy a few more weeks of dating bliss before things go sour, Swift writes a breakup anthem and moves on to the next unsuspecting hit maker.

Enjoy it while you can, young lovers.

10:00 AM -- Harry and Taylor left the same hotel moments ago, just minutes apart from each other.

With rumors of a secret relationship in full swing, Taylor Swift and One Direction heartthrob Harry Styles were spotted in a FULL-ON CANOODLING SESSION in NYC this weekend.

While there appeared to be no hand-holding or lip-smoochery, the two seemed to be very into each other during a stroll through Central Park.

If ... and only IF ... they dated, Harry would follow in a long line of Taylor's celebrity conquests ... which includes John Mayer, Jake Gyllenhaal, Joe Jonas, Taylor Lautner and Cory Monteith.
