Nothing comes between the One Direction boys, not even Taylor Swift's f-bomb at the 2013 VMAs on MTV Sunday night, which was caught on camera when One Direction got on stage to present an award.

One Direction band mates rushed to Harry Styles' defense the night after the 2013 VMA, at the premiere of their "This Is Us" concert documentary in New York City.

The One Direction boys joked to Vulture, acting as though Taylor Swift was swearing at Niall Horan, instead of her ex-boyfriend Harry Styles, when she saw the boys onstage.

Liam Payne feigned anger: "When she said those things about Niall [Horan], we were very, very pissed off."

Horan added, "I was so upset that she would go writing songs about me after all we've been through."

And Liam continues: "Hashtag get over it."

The One Direction boys joked to Us Weekly too at the New York premiere.

"We were a bit confused," Louis Tomlinson told Us Weekly. "We thought she was actually calling out Niall [Horan] so the whole thing's a bit confusing."

Liam Payne added a little more seriously: "I just thought it was a bit not needed. I mean, you just won an award, it's like, concentrate on yourself!"

When a reporter asked if Swift's behavior was "lame," Payne agreed, saying, "Yeah."

At the VMAs, Styles, 19, presented an award with One Direction onstage, and Swift, sitting beside her best friend Selena Gomez in the audience, was filmed appearing to mouth "shut the f--- up!," Us Weekly reports.

Swift and Styles broke up in early January after a couple months of dating.

Ironically, Hollywood Life reports that Harry and Taylor posed together for a picture with Ed Sheeran and a friend at Robin Thicke's after party Sunday night, and reportedly went out for dinner and a mocktail.

Styles has tastefully not commented on the topic.
