Taylor Swift's diss heard 'round the world from the 2013 Grammys may have launched a thousand Tumblr rants, but one reaction she won't get? The one she probably wants the most. One Direction singer Harry Styles, whose British accent she mocked onstage during her circus act opening performance at the ceremony, is simply ignoring her.

Hazza's bandmates urged him not to stoop to her level and draw any more attention to their failed relationship -- which is, ironically, something Swift always claims to want to keep private, despite her cryptic tweets and public jibe.

“They've all advised him to be the bigger person and not to wash his dirty laundry in public -- it’s just tacky and embarrassing," a source close 1D told Radar Online.

“With the media circus that surrounded Harry and Taylor when they were together, the boys were a little miffed that it distracted fans from the band and what they were all about," the source said. The insider added, "Of course, when it didn't work out, there was a sense of relief because they knew that, along with Harry, they could all move on."

Somewhat unsurprisingly, the source also quipped, “It’s only Taylor now that seems to clinging on to their failed relationship, and Harry has been told to keep his thoughts private."

The One Direction boys have a point. It's best to take the high road until it gives you a nosebleed -- especially when you're dealing with someone as famous (and as apparently smug about it) as T-Swizzle.
